Material Notes:
TRA-BOND 2202 is a low viscosity, high temperature cure epoxy resin system developed for rigid laminating, filament winding, potting and bonding applications where a clear, almost transparent adhesive system with good mechanical and electrical properties plus good heat resistance is required. This all liquid system has a long pot life and is easily mixed and handled at room temperature, however a final elevated temperature cure is REQUIRED for the complete development of its superior properties. TRA-BOND 2202 bonds to metals, glass, ceramics and other high temperature resistant products. Fully cured TRA-BOND 2202 is a strong, durable electrical insulator, and it provides excellent resistance to weather, water, vapors and gases, most petroleum products and solvents, salts, mild acids and alkalis, and many other organic and inorganic compounds. An additional post-cure of 4 hours at 145°C is recommended when application temperatures higher than 145°C are anticipated.Information provided by Tra-Con Inc.
