Tra-Con Tra-Bond F253 Color Keyed High Temperature Epoxy Adhesive

TRA-BOND F253 is a low viscosity, high temperature, two-part epoxy formulation that changes color during the curing process to indicate cure status. The unmixed components are light yellow; the mixture is green/blue; and the fully cured adhesive is reddish-amber. It exhibits excellent wicking, and develops strong, tough mechanically stable bonds to a wide variety of fiber optic and optical materials that includes most metals, ceramics, glass and many plastics. In addition, TRA-BOND F253 has good impact and thermal shock resistance, demonstrates low stress, and yields excellent pot and polish connections. It is also resistant to water and weathering, vapors and gases, most petroleum products, and an extended range of organic and inorganic environments. An additional post-cure of 30 minutes at 150°C is recommended when application temperatures higher than 150°C are anticipated.Information provided by Tra-Con Inc.
