Product description

C640 is a flexible cure cyanate ester component prepreg, suitable for curing between 70-135°C (158-275°F). C640 is capable of withstanding very high temperatures and is inherently flame retardant. After a suitable post-cure the glass transition temperature can be increased to as high as 335°C (635°F).

The medium viscosity C640 resin is pre-impregnated into high performance fibers such as carbon, glass and aramid.
