Resin System

October 1, 2008

Epsilon 99100 benzoxazine RTM/VARTM resin system from Henkel Corp. (Bay Point, CA) is designed for composite structure in aerospace applications. The resin is stable at ambient temperatures for over a year as a one-part resin. The system features a broad processing window for large parts and intricate shapes, viscosity stability, low heat release during cure, low cure shrinkage for improved translation of strength in the final part, fire retardance for aircraft fuselage and interior applications, high hot/wet property retention, improved UV resistance, and thermal resistance. The 180°C cure resin is also resistant to solvents, has high compressive strength and modulus, and has hot/wet glass transition temperature of 165°C.
