Material Notes:
TRA-BOND 2212 was developed for high temperature bonding, laminating, filament winding and potting applications where the combination of good physical and mechanical properties plus superior wetting and handling characteristics is required. This dark amber, all liquid formulation contains no solvents, and is easily mixed, handled and applied at room temperature, however a final elevated-temperature cure step is required for complete cure. TRA-BOND 2212 develops strong, tough bonds to metals, glass and glass fabrics, ceramics and many other electronic an aerospace materials. The fully cured adhesive exhibits low weight loss and an improved retention of mechanical properties at elevated service temperatures. It also displays excellent chemical resistance and low permeability to gases and vapors coupled with superior electrical insulation properties. In addition, TRA-BOND 2212 provides very good resistance to water, weather, jet fuels, most petroleum products, salt solutions, mild acids and alkalis, and many other organic and inorganic compounds. For masses over 1/4 gram, step cure the material for 2 hours @ 75°C, followed by 1 hour @ 150°C. This step cure schedule can also be used for low stress applications.Information provided by Tra-Con Inc.
