STORAGE AND PREPARATION OF COATING PROCESS
1.1
QUALITY CONTROL OF MATERIALS ON RECEIPT
Product
No.:
Productseries/Article
series/Article No.:
-11551155
New supplies should be controlled with respect to the following parameter:
a)
Actual quantity supplied should correspond to the quantity indicated on the delivery note.
b)
Packaging supplied should be checked visually, so as to ensure that they were not damaged
during transport.
c)
Supply viscosity should be conform to the values indicated in the according technical data
sheet.
1.2
STORAGE
Material should preferably be stored at temperatures between 15° C and 25° C (59°F and 77 °F).
The warehouse should meet official regulations regarding storage. Storage should further be
organised according to the principle first in -first out, so that older batches are processed first.
When planning coating jobs, it should be taken into consideration that colour and degree of gloss of
different batches may vary slightly. For this reason coating of diverse parts of one product should - if
possible - only be coated with lacquer out of one batch.
If shelf life of the coating to be processed has already expired (we grant 6 months from
manufacturing date), it should be verified in time whether lacquer is still in good condition and allows
further processing. Respective criteria are: viscosity, a smooth and homogeneous surface as well as
colour of a trial coating. It should be ensured that material is homogenised thoroughly!
1.3
PREPARATIONS FOR COATING PROCESS
Prior to processing material must be brought to room temperature and stirred thoroughly High-speed
stirrers are to be preferred. Slowly running stirrers - integrated in many pressure tanks - are not
suitable for homogenisation, in particular in case of sedimentation. It is to be ensured that no
humidity comes into the material, as this negatively influences shelf life. Until next use, drums
should be closed again tightly.
In general, an adjustment of viscosity is not necessary, as material is supplied at application
viscosity. The system used for application of the coating should be equipped with a pre-filter with
large mesh size (> 500 µm/ < 35 mesh).
QW-4.2-Nr.528e-1-08/08
QW-4.2-Nr.528e-1-08/08
Should coating material out of drums that had already been opened be used, please note that any
skin that may have formed can not be stirred into the material again, but has to be removed.

2.
COATING LINES
senotherm® coatings of series -1155- can be successfully applied by means of a variety of
application methods.
In general, however, this coating is applied via spray lines with conventional high-pressure air
atomization or via HVLP-systems. Other application systems are – after specific testing and
verification – possible. For the sealing of sockets and pipe couplings Teflon tape in combination with
Loctite glue has proven of value in practice. Mere hamp packs or self-cutting threads are not suited.
Depending on the geometry of the items or desired throughput /passage, it is also possible to apply
material via customary air-assist electrostatic systems. However, as the products are not adjusted for
ESTA spray, it would be reasonable to inform us on this particular requirement prior to placing the
order, so as to avoid any processing problems.
An application by means of brush and flow coating is - because of the poor surface quality that would
be achieved - generally not suitable. Due to the materials limited stability with regard to incorporation
of humidity, an application by means of dip coating is impossible.
Standard types are also available in spray cans.
All parts carrying the lacquer, as e.g. pipes, seals etc. must offer sufficient resistance against
hydrocarbons as e.g. xylene and benzine.
Prior to application of another system, the line should be cleaned with thinner 00-9597-100.066 or
another suitable quality.

3.
SUBSTRATES
This coating material allows use of the following substrates: aluminium, steel, stainless steel as well
as temperature-resistant combined materials e.g. aluminised steel, chromized steel and Galvalumes.
As is the case with most coating processes, the kind and quality of pretreatment has a considerable
influence on the quality of the final finish and hence its durability. The enclosed list indicates possible
combinations of substrates and pretreatments. In general, abrasive pretreatments lead to better
mechanical properties, however, minimum necessity is at any rate a clean, metallically pure
substrate that is further free from grease. For colours such as white, blue, red etc. a sanding is
imperative. Corrosion products (layers of rust or mill scale etc.) must be completely removed prior to
application.
As the requirements, depending on the end use, vary considerably, each new material and
processing combination should be tested with respect to its suitability for the respective application
prior to use. As a rule, substrates should - after pretreatment - be coated as soon as possible in
order to avoid belated contamination, the formation of oxide layers and the addition of humidity. If an
intermediate storage is necessary, items should be stored in tempered rooms with only insignificant
temperature changes, to avoid the formation of water of condensation.

PROCESSING
If possible, application should be made under constant conditions as e.g. temperature and
atmospheric humidity. As this is hardly fully feasible in practice, processing parameter as for instance
supply and atomizing pressure must be adjusted under consideration of the changed conditions.
PROCESSING SHOULD PREFERABLY BE MADE OUT OF CLOSED SYSTEMS AS E.G. PRESSURE TANKS, IN
ORDER TO REDUCE THE INCORPORATION OF HUMIDITY AS MUCH AS POSSIBLE. THIS INCORPORATION OF
HUMIDITY NEGATIVELY INFLUENCES STORAGE STABILITY. IF HAND GUNS ARE USED, DRUMS MUST BE CLOSED
AGAIN TIGHTLY AFTER EACH TAKING OUT OF LACQUER. SPRAY GUNS SHOULD ALSO BE CLOSED DURING
APPLICATION. TUBES AND PIPES MUST BE CLEANED AND RINSED AT THE END OF THE WORKING SHIFT AND
PRIOR TO LONGER INTERRUPTIONS/ BREAKS OF WORK.
For conventional high-pressure atomisation nozzle sizes of 1 - 2 mm with atomizing pressures of 2 5 bar (30-70 Psi) can be used. In practice nozzle sizes of 1,3 - 1,5 mm and atomizing pressures of
2,5 - 4 bar (36 – 58 PSI) have proven to be advantageous.
AS A RULE, IT IS TO BE TAKEN CARE THAT MAXIMUM FILM THICKNESS IS NOT EXCEEDED, AS THIS DOES NOT
ONLY INCREASE MATERIAL COST, BUT MAY ALSO LEAD TO QUALITY PROBLEMS AS FOR INSTANCE CRACKING,
PEELING OR ROLLING OFF IF EXPOSED TO RAPIDLY CHANGING TEMPERATURES.
5.
CURE
senotherm® paints of series -1155- are airdrying.
QW-4.2-Nr.528e-1-08/08
QW-4.2-Nr.528e-1-08/08
Under standard conditions (20° C (68 °F) and 50 % relative atmospheric humidity) and if applied at
film thickness of 25 microns( 1 mil), films are dust dry after approx. 20-30 minutes and dry to touch
after approx. 1-2 hrs.
During airdrying methylalcohol is released. Therefore it is necessary to take care for proper
ventilation!
In practice, however, these values may – especially depending on the ambient temperature, the
atmospheric humidity and the dry film thickness – vary.
At temperatures below 10° C (50 °F) there is no sufficient through drying
Full properties are achieved after airdrying of 7 days. If items are subjected to temperature prior to
complete drying (at least 2 days), subject system may also release visible fumes when being put into
operation for the first time.
