Material Notes:
TRA-CAST 3101 is an easy-to-use, room temperature cure, rigid, low viscosity, 100% solids (no solvents) epoxy resin and hardener system with excellent mechanical and electrical properties. It is recommended for structural and electronic casting and encapsulating applications that require its excellent wetting and fluidity, good thermal expansion coefficients, and improved thermal shock resistance properties. TRA-CAST 3101 is readily mixed, handled and cured at room temperature, and it adheres to a wide range of materials including most metals, glass, ceramics and many plastics. Fully cured TRA-CAST 3101 is a strong, tough, durable electrical insulator which is also highly resistant to weather, water, gases and vapors, petroleum lubricants and fuels and many mild acids and alkalis.Information provided by Tra-Con Inc.
