Toray TC420
Toray TC420 is a flow-controlled high temperature cyanate ester resin, toughened to resist microcracking. TC420 is specifically formulated to facilitate production of large out-of-autoclave structures. It can act as a self-adhesive system and is resistant to microcracking. This resin represents a new family of next generation high temperature resins, film adhesives, syntactic paste and expanding foams for ultra-high temperature conditions. TC420 is easy to process, and yields low void laminates with a flexible cure cycle under vacuum-only pressure. This system is also autoclave processable. TC420 is an attractive alternative to bismaleimide (BMI) and polyimide resins.
