Tra-Con Tra-Bond F253HV Color Keyed High Temperature Epoxy Adhesive

TRA-BOND F253HV is a clear, high temperature, two-part epoxy formulation that changes colors 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 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 F253HV has good impact and thermal shock resistance, demonstrates low stress, and yields excellent pot and polish connections. It also is 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.
