1 Invincible. The next generation of thermoset matrix resins

2 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 T G 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 T G 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. Prepreg production Dry fabric Drying Resin solution Impregnated fabric Dry prepreg Parts production Autoclave Compression molding press Our Partner 2

3 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 <.5 % and superior characteristics compared to stateof-the-art phenolic compounds, CALIDUR also demonstrates very good mechanical properties. Prepreg characteristics Tackiness No tack Storage stability Stable for at least 6 months at 8 C Curing cycle Wide range of curing conditions possible T G after curing (3 mins at 15 C) * DSC 152 C T G after curing (1 mins at 18 C) * DSC 163 C T G after curing (45 mins at 18 C) * DSC 187 C * 1 layer glass fiber prepreg (3gsm, E-Glass HexForce 7781, 8H satin) 3
