Product description

TenCate C740 is a cyanate ester resin system for cures at 135°C (275°F), pre-impregnated into high performance fibres such as carbon, glass and aramid. The system is capable of withstanding very high temperatures and is inherently flame-retardant. After a suitable postcure the glass transition temperature can be increased to as high as 325°C (617°F).
