TRA-BOND 2248 is a thixotropic, high temperature cure, 100% solids epoxy resin system that provides strong, tough bonds between a wide range of materials (includes metals, glass, ceramics, and many plastics). This adhesive is recommended for bonding applications up to 190°C where good high and low temperature mechanical and electrical properties are required. It is an all liquid system that is easily mixed and handled and applied at room temperature although a final high-temperature cure is REQUIRED for satisfactory bonds. Fully cured TRA- BOND 2248 has excellent impact and thermal shock resistance, low permeability to gases and vapors, and outstanding resistance to water, weather, oxygen and ozone, most petroleum solvents and fuels, mild acids and alkalis, and many other organic and inorganic compounds. This system complies with specification ASTM E-595-90 for NASA outgassing acceptability. An additional post-cure of 2 hours at 125°C is recommended when application temperatures higher than 125°C are anticipated. Information provided by Tra-Con Inc. |
