TenCate TC420
Cyanate Ester

Download datasheet (PDF)
Product description

TC420 is a flow controlled high temperature cyanate ester resin, toughened to resist microcracking. TC420 is specifically formulated for out of autoclave large structure, can act as a self adhesive system and is resistant to microcracking. This resin improves on the success of EX-1505 resin, and represents a new family of next generation high temperature resins, film adhesives, syntactic paste and expanding foams for ultra high temperature conditions. This resin system is easy to process and yields low void laminates with a flexible cure cycle under vacuum only pressure. This system is also autoclave processable.

Product benefits/features
  • High temperature stability and resistance to microcracking
  • Low void content in vacuum pressure cure conditions (out of autoclave)
  • Utilizes standard 350°F (177°C) cure temperature with optional free standing post cure at 450-500°F (232-260°C) for 90 minutes for full high temperature capability
  • Capable of 500°F (260°C) continuous service with short term capability to 600°F (316°C)
