Why Use Catalysts?
Today’s need for
E
high solids and
Energy
waterborne
Required
Without
coatings requires
Catalyst
greater use of high
reactivity, low
viscosity resins
and crosslinkers.
Conversion of
these systems into
ECAT
Energy Required
tough, chemically
With Catalyst
resistant, high
performance coatings at reduced cure temperatures can be accomplished
with the use of a catalyst.
Acrylics, alkyds, epoxies and polyesters with reactive
functional groups, such as hydroxyl carbamate, siloxane
or amide can be reacted with melamine, urea and benzoguanamine crosslinkers. The proper use of catalysts
can facilitate the crosslinking reaction resulting in the
following benefits:
Catalyst By Acid Type
Acid

Shorter cure schedules

Lower cure temperatures for thermoset high
solids and waterborne coatings

Energy savings

Improved hardness, gloss, humidity and
corrosion resistance

Free Acid Or Latent Catalyst?
SO3H
While acid catalysts provide the fastest cure and lower
curing temperatures, blocked or latent catalysts are
typically chosen for systems requiring greater package
stability. In addition, troublesome catalyst-pigment
interaction can be reduced or eliminated with the use
of blocked catalysts.
As can be seen in the table which follows, King’s
catalyst line is based upon a variety of acids. The
middle column denotes the free acid versions while the
far right column shows amine blocked or covalently
bonded derivatives for applications requiring extended
package stability.

The type of crosslinker used will also affect the choice of
catalyst. High solids and waterborne coatings are typically formulated with monomeric crosslinkers such as
hexa(methoxymethyl)melamine (HMMM) or mixed ether
melamine; reaction of these crosslinkers with hydroxy or
carbamate functional groups is best achieved with strong
acid catalysts like DNNDSA or p-TSA.
More reactive crosslinkers, which are more polymeric but
contain high levels of -NH groups, respond better to a
weaker acid such as acid phosphates or low dosages of
amine blocked sulfonic acids.

The chemical structure of the catalyst, as well as the
quantity used, can have a profound impact on film properties such as adhesion, corrosion resistance, flexibility and
impact resistance. These observations are apparent not
only among varying acid types but also among different
products within the same chemical family.

Formulating Information - Use Levels
The two charts which follow provide general information on typical catalyst use levels by acid type based on a 30 minute
cure schedule for a typical binder resin/HMMM ratio of 75/25. The percentage of catalyst shown is as supplied based on
total resin solids. A ladder study of catalyst levels should be conducted to optimize the formulation.
Do not over catalyze. Using too much catalyst can be a costly mistake and one that can cause film properties to suffer
significantly.

In general, the time and temperature conditions of cure will determine the correct catalyst for the application. Strong
acids with typical pKa strengths of approximately 0.5-0.7 should give equivalent rates of cure at equal molar concentrations of the acid group. Blocked catalysts will demand higher temperatures for full activation, and the pKa of the
blocking agent attached to the acid will also influence the rate of reactivity.

Formulating Information - Incorporation
Methods of Incorporation
As with any component in a coating, the level, method and order of addition may mean the difference between formulation success or failure. When incorporating acid and blocked acid catalysts the following factors should be considered:



Method of mixing
Solvents present
Pigments present



pH sensitivity of resins
Temperature at time of addition
Stability/pot life requirements
It is generally good practice in high solids coatings to pre-dilute a catalyst with butanol or isopropanol before adding it
to the paint. Stirring during the addition can help avoid pigment shock and the generation of “hot spots” - although
with amine neutralized or blocked catalysts, these problems are rare.
In some cases, blocked catalysts can even be added to the pigment grind for uniform dispersion and improved
solubility. The decomposition or reactivity temperature of the catalyst, though, should be safely above the grind
temperature.
King Industries’ products are typically supplied in a common solvent such as alcohol that will allow simple
post-addition after milling of pigments and letdown with resins and solvents.
Systems that are viscous, or those sensitive to pH differences induced by an acid component. Such systems
often require further pre-dilution with alcohol. Blend the catalyst with an alcohol such as n-butanol or isoproponal at
1:1 ratio. Extremely sensitive systems may require the use of a blocked acid catalyst with a neutral or basic pH value.
Mixed solvent systems with some products that are less soluble than others. In these cases, incorporate the
catalyst in the more compatible resins and solvents before adding less soluble components.
Waterborne systems that can suffer from rapid pH changes. Waterborne systems are generally formulated to a
final pH range of 8-9. Use of a blocked catalyst in such systems will prevent the rapid pH changes that can upset the
balance of resin solubility and cause a flocculated or gelled formulation.
Formulations that include a pigment with high oil absorption characteristics. Hydrophilic catalysts such as
p-TSA are not recommended in such cases. A more hydrophobic blocked catalyst such as DNNSA is recommended.
The chart below shows the relative hydrophobicity of different catalyst types.

both with and without 1.8% 2,4-Pentanedione. While pot
life extension of the DBTDL system was evident, the
increase was much more significant in the K-KAT 5218
system.
K-KAT XK-614 has demonstrated excellent hydrolytic
stability and an increased tendency to selectively
accelerate the polyol/isocyanate reaction in the

Optimum synergy with pot life extenders such

A good indicator of pot life, or workable time, of a 2K
waterborne urethane paint is gloss of cured films cast
with aged paint. After the two components are combined, the aging process begins in the pot as polyol and
water compete for free isocyanate groups. Gloss of
films cast with aged paint is reduced as more water
reacts with isocyanate in the pot.

K-FLEX® POLYESTER POLYOLS
K-FLEX 100% active polyester polyols are used primarily
as modifiers for acrylic, alkyd, epoxy and polyester formulations with melamine or polyisocyanate crosslinkers.
Typical modification levels are 5 to 15% on total resin
solids.
Most K-FLEX polyesters have a narrow molecular weight
distribution (MWD). As a result, they have excellent compatibility with a wide range of resins and excellent solubility
across a broad range of solvents and solubility parameters
including some of the more difficult solvents like
PC - propylene carbonate, DMC - dimethyl carbonate,
acetone, TBA - t-butyl acetate and p-Chlorobenzotrifluoride
(OXSOL® 100*). Additionally, as shown in the photo,
K-FLEX polyesters can be
used to compatibilize other
resins into these solvents.
Lowest viscosity for lowest VOC. Softest films.
Offers high hardness and high modulus in 2K urethanes.
Optically clear systems. Designed to provide long pot life in 2K
urethanes and to prevent yellowing caused by benzotriazole type
UV absorbers.

Formulating With K-FLEX Modifiers
K-FLEX polyesters and urethane diols can be added to
the grind or letdown with no special incorporation techniques. To formulate a high solids pigment grind the
addition of at least 5% of a high solids acrylic resin is
recommended in combination with a K-SPERSE
dispersant.

K-FLEX polyester polyols are effective modifiers for most
2-component polyurethane systems. Performance advantages include lower VOC, improved adhesion, increased
flexibility and elongation, higher tensile strength, humidity
resistance and abrasion resistance.
K-FLEX polyester polyols have proven to be effective
in light stable cast elastomers where a combination of
optical clarity and mechanical
properties are sought. In addition
to the mechanical properties
shown in the table that follows,
K-FLEX XM-359 offers excellent
optical clarity and transparency as
shown in the photo to the left.

The high hydroxyl number of K-FLEX products necessitate a careful calculation of the isocyanate ratio to
assure complete crosslinking of the polyol hydroxyl
groups. A NCO:OH ratio of 1.04:1.00 to 1.10:1.00 is
typical. K-FLEX A307 has the lowest isocyanate
demand.

Adhesion Studies
K-FLEX polyester polyols have demonstrated excellent
adhesion to many substrates including many plastics.
K-FLEX 188, A307 and A308 were found to have excellent
adhesion to Xenoy®*, ABS, RIM, RRIM, SMC, PVC and
polycarbonate using both an HMMM crosslinker and HDI
isocyanurate crosslinker.
* Xenoy® is a registered trademark of SABIC Innovative Plastics
Melamine Ratio
Due to the high hydroxyl number of K-FLEX modifiers
(with the exception of A307), a ratio of K-FLEX / HMMM
of 60 / 40 is normally recommended. This provides a
1 / 1 equivalent of hydroxyl group to methylol group,
assuming an equivalent weight of 160 g/eq for HMMM.
Properties may be adjusted for higher hardness with a
lower K-FLEX / HMMM ratio or improved flexibility with
a higher K-FLEX / HMMM ratio. K-FLEX A307 has a
lower crossliner demand and therefore does not require
the higher levels of HMMM. Adjustments in melamine
levels should be made based on equivalent weights for
other types of melamines (high imino, polymeric, etc…).

The K-FLEX UD aliphatic urethane backbone provides
excellent hydrolytic stability. It also allows the incorporation of aliphatic urethane functionality without the use of
isocyanates.
K-FLEX urethane diols are soluble in water and most
polar organic solvents, in the absence of surfactants,
neutralizing amines and co-solvents. They are not
soluble in more hydrophobic solvents like aliphatic
hydrocarbons or aromatics. However, varying levels of
hydrophobic solvents can be tolerated depending on the
solubility parameters of the other solvents present.

K-FLEX® URETHANE DIOLS
K-FLEX Urethane diols are low molecular weight (MW)
diols with an aliphatic urethane backbone and a narrow
MW distribution. They allow the formulation of higher
solids, lower VOC waterborne (WB) coatings. They have
been developed to help achieve VOC compliance with the
added benefit of improved film performance. Their low
molecular weight provides a higher crosslink density
yielding harder films with greater exterior durability. The
urethane diols are useful in various industrial systems,
such as:

K-PURE CXC Catalysts for epoxy/hydroxyl and anhydride systems are most commonly used in solvent less
systems.
One component, high solids or solvent less systems for
high speed or low temperature applications can be
obtained using this technology.
K-PURE CXC-1612 and CXC-1614
The unique blocking group under goes a chemical
re-arrangement upon activation, that eliminates any
volatile components to be generated during cure.
These catalysts are based on super acids, hexafluoroantimonate or triflic acid and can be used in conjunction with
cycloaliphatic epoxies, glycidyl ester and glycidyl ether
resins.
Polymerization of the epoxy resin occurs via a cationic
mechanism, thus allowing co-polymerization with hydroxyl, lactone, oxetane or vinyl functional groups.
Additional Offerings
King offers additional catalysts for epoxy systems under its
K-PURE® tradename. Found on King’s web site, this family
of catalysts developed for the electronics industry includes
non-antimony catalysts with higher activation temperatures
and higher purity.

Formulating Considerations
Solid Catalysts (CXC-1612 and 1614) - These solid catalysts are soluble in most liquid epoxies at the recommended
use levels, but making a concentrate with reactive diluents
makes screening easier. Propylene carbonate is a common
diluent, but liquid anhydrides and citrate esters are also suitable. These concentrated solutions are less stable than the
solid catalyst (manifested by color change), and aged concentrates may change the formulation stability. Therefore, it
is recommended that all pre-dilutions be made and used as
needed. Pre-diluting in di-functional epoxy or vinyl ether
functional diluents is not recommended.
Base Sensitivity - Super acids (CXC-1612, 1614 and
1615) are sensitive to basic materials. Thus, cure can be
inhibited by basic substrates, pigments or resins.
Ambient Cure - These catalysts are not designed to
cure epoxy systems at ambient temperatures.

NACORR® Rust & Corrosion Inhibitors
NACORR® RUST & CORROSION INHIBITORS
Mechanism
The NACORR molecules have a polar metal sulfonate
group and a long hydrophobic tail. The NACORR products prevent corrosion by two distinct mechanisms
including:

Polar metal sulfonate is attracted to the metal substrate where it helps to electrically passivate any potential
anodic sites
Introduction
King Industries’ NACORR® Rust & Corrosion Inhibitors
provide formulators the means to impart corrosion resistance to aqueous, non-aqueous and powder systems.
NACORR can be used as the primary corrosion inhibitor
or in combination with environmentally friendly anticorrosive pigments. They are compatible with a wide variety of resins used in primers and direct to metal topcoats
for a multitude of industrial applications. Benefits include:






The hydrophobic tail is oriented outward away from
the metal substrate, excluding water from any potential
anodic sites. This eliminates the electrolyte, one of the 4
required elements for corrosion (anode, cathode, conductor and electrolyte)
Improved corrosion protection in clearcoats and
highly pigmented systems
Liquid materials make for easier incorporation
Synergy with anti-corrosive pigments to replace
chromates and other environmentally
unacceptable anti-corrosive pigments
Improved pigment dispersion and gloss when
added to the pigment grind (for solventborne
coatings)
Enhanced cure rates of amino crosslinked
systems, especially with NACORR 1552 (zinc salt)
Hydrophobic Barrier Layer

NACORR's are metal or amine salts of a hydrophobic
sulfonic acid. They are available in different solvents to
accommodate the broad range of coating technologies
currently used. Standard solvents are Mineral Spirits or
2-Butoxyethanol.

NACORR Synergy With Anti-corrosive Pigments
To achieve the level of corrosion resistance found with
chromates and other environmentally unacceptable anticorrosive pigments, the NACORR products are often
used synergistically with more environmentally friendly
anti-corrosive pigments.
Please find below a table of King Industries, Inc. formulations demonstrating synergy with a wide variety of commonly used anti-corrosive pigments, including; borates,
phosphosilicates and phosphates.

Use Levels & Incorporation
Generally, addition levels of 1-3% based on total weight of the paint are effective in enhancing corrosion protection. Due
to the polarity of the metal sulfonate, highly pigmented systems or pigments with high surface areas may require higher
levels of NACORR. This is due to the affinity of NACORR for the pigment surface. If active pigments are reduced or
eliminated, they should be replaced with inert pigments to maintain solids and critical pigment volume concentrations.
The NACORR products are based on a variety of different metal salts. The NACORR metal salts appear to be very
system specific. Some work better than others, depending on the resin system, type of anti-corrosive pigment, and
other formulation components. It is best to evaluate several of the NACORR products in your formulation to find the best
performing product. Once a product is selected, it can be optimized by conducting a ladder study to determine a use
level that best meets your performance needs.
SYSTEM
Incorporation Method
Solvent Based
Can be post added with mild agitation or added to mill base.
Water Reducible
With Water In Mill Base
If possible, remove water from base and add it to the letdown. Otherwise post-add under high agitation.

K-Sperse 152 – Synergist and Catalytic Effects
K-Sperse 152 is very effective as a synergist with polymeric
dispersants to optimize carbon black and red shade phtalo
blue dispersions.
Formulators should be aware of a possible catalytic effect
with K-Sperse 152. The zinc in K-Sperse 152 may
complex with the driers and accelerators used in air
oxidized paints. K-Sperse 152 can also contribute to the
cure response in thermoset HMMM systems. K-Sperse
131/132 should be used in place of K-Sperse 152 to avoid
these catalytic effects.

DISPARLON® Additives
for Surface Control and Thixotropy
Disparlon additives are manufactured by Kusumoto
Chemicals Ltd. of Tokyo, Japan. Through a technology
partnership spanning over three decades, King Industries,
Inc. serves as exclusive sales, technical service and
marketing arm in North and South America.
DISPARLON® Thixotropes
Introduction
Disparlon thixotropes offer today’s formulators a wide
choice of unique products for conventional, high solids
and aqueous coatings, as well as specialty additives for
inks, adhesives, gel-coats, sealants and caulks. Their
primary advantages over other types of thixotropes
(organo-clay, castor wax or fumed silica) are:





Superior shear thinning
Non-seeding
Maximum anti-sagging/anti-settling
Excellent stability on aging
Superior performance in high gloss systems
Disparlon anti-sag and anti-settling agents can be
characterized into two functional types:
NON-PIGMENT DEPENDENT - These types of
thixotropes, which include polyamide powders and
pastes function by forming a three dimensional network.
Since these thixotropes are non-associative by nature,
they do not require the presence of pigments or fillers to
function. These thixotropes can be used in pigmented or
clear systems.
PIGMENT DEPENDENT - These products are dependent
on the type and level of pigment in the formulation, since
they adsorb onto pigment surfaces to provide thickening
efficiency.
Also included in the pigment dependent type are
“Hybrids”, polyamide waxes that are coated with pigment
dependent polyethylene waxes. These “Hybrids” offer
excellent pigment suspension plus sag control.
DISPARLON® ADDITIVES
The Disparlon trade name is applied to a series of
functional additives used in paint, ink, adhesive and
sealant markets worldwide. Major product types include,
thixotropes, dispersants and surface control agents.
Originally designed for solvent systems, the Disparlon line
has expanded in recent years to include high performance
additives used in aqueous, powder and uv systems.

Disparlon Powder Polyamide Thixotropes
Powder thixotropes (100% active) require heat and/or
hydrogen bonding to activate. By heating these thixotropes
to the appropriate temperature in the formulation using
good agitation, the polyamide will swell and disperse
(activate), and provide very efficient thickening.
Hydrogen bonding from materials such as amine
functional and hydroxyl functional solvents and resins will
help lower the activation temperature. Products are
available for coatings, sealants and adhesives.

Powder Thixotropes Incorporation
The polyamide powder thixotropes need to be activated
(swelled and dispersed) in the system. Add the powder to
the pigment grind portion of the formulation. While
grinding the pigments, allow the temperature of the grind
to rise to the temperatures shown in the selection chart
above. Once at the “activation temperature” continue to
grind for 15 minutes to get full activation of the polyamide.
After activating the polyamide, it is generally best to mix
slowly during the first 20ºC of cool down. The slow mixing
during cool down will give the system the most uniform
and reproducible rheology.
Please note, these materials will activate at lower
temperatures than shown in the chart when in the
presence of alcohols or amines, due to increased
hydrogen bonding.
Disparlon Preactivated Polyamide Thixotropes
The preactivated polyamide thixotropes are ready to use.
They do not require heat for activation, and can be added
directly to the formulation. These materials can be used
in clear as well as pigmented systems, and offer good
anti-sag and anti-settling properties. The preactivated
polyamides are commonly used in coatings such as aerosol paints, clear coats, architectural stains, auto refinish,
industrial and maintenance coatings. They can also be
used to orient metallic pigments and flattening pigments
in oil modified urethanes.

Disparlon Dispersants & Anti-flood/Anti-float Additives
The Disparlon dispersing agents are formulated for
effectiveness depending upon the pigment type and the
system’s polarity, to:




Improve color strength and gloss
Prevent flocculation
Reduce grinding time
Reduce-eliminate flood & float problems
PRODUCT
Composition
While all products are well suited in eliminating floating
problems, each has specific strengths in terms of other
characteristics such as the prevention of flooding and
Bernard cell formation, as well as imparting superior
pigment wetting and stabilization of the pigment
dispersion. Dispersants should be added to the vehicle
before pigment addition; KS-273N and KS-873N can be
post added.
