Invincible. The next generation of thermoset matrix resins

Invincible.
The next generation of
thermoset matrix resins
CALIDUR® polyetheramide resins
CALIDUR® is a new class of thermoset matrix resins that combines the high flame
retardancy of phenolic resins with the mechanical properties of high TG epoxy resins.
Benefits
CALIDUR® provides much greater design flexibility for carbon fiber and glass fiber
composite structures in aircraft and other transportation interior applications.
Properties
• Intrinsic FST performance
• High TG
• Excellent surface quality
Processing
• Rapid processing and curing
• Formaldehyde-free
• Thermoformable
• Storage-stable at 8°C
CALIDUR® is supplied as a resin solution or in powder form. Prepregs with
various fiber reinforcements are available via our partner c-m-p GmbH.

In addition to enabling short production
cycles, CALIDUR® does not require binders
while providing greater flexibility across a
wide range of curing temperatures.
With a very low shrinkage of < 0.5 % and
superior characteristics compared to stateof-the-art phenolic compounds, CALIDUR®
also demonstrates very good mechanical
properties.

The exceptional properties of CALIDUR® make it ideal
for applications that require both superior resistance to
flammability, especially smoke density, and outstanding
mechanical strength.
