Material Notes:
TRA-BOND 2105 is a clear, medium viscosity epoxy adhesive which contains no solvents or other additives which can be harmful to the environment or to its users. It has excellent adhesion to glass, ceramics, most plastics and metals, and is particularly recommended for applications where dependable, reputable performance is required, including assembly and repair of fiber optic connectors, high performance electronic and aerospace systems, medical device assembly, and for structural laminating applications. The fully cured TRA-BOND 2105 is a good electrical insulator, has a high glass transition temperature for good rigidity and provides excellent resistance to weather, galvanic action, salt solutions and many chemicals including mild acids and alkalis, petroleum solvents, lubricating oils, jet fuels, gasoline and alcohol.
