TenCate C640
Cyanate Ester

Download datasheet (PDF)
Product description

TenCate C640 is a cyanate ester resin system suitable for curing between 70°C (158°F) and 135°C (275°F). The medium viscosity resin is 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 335°C (635°F).

Product benefits/features
  • Inherently flame retardant with low toxic gas and smoke generation
  • Good dimensional stability and thermal durability up to 250ºC (482ºF) after post-cure
  • Flexible low to medium cure schedules 70°C (158°F) to 135°C (275°F)
