Material Notes:
TRA-BOND 5126 AEROSPACE-GRADE EPOXY ADHESIVE is a two-part, clear (amber), medium viscosity, aerospace-grade epoxy adhesive system recommended for bonding a wide variety of materials for structural and non-structural applications where good wetting, toughness and superior mechanical properties are required. This high performance adhesive is mixed and used at room temperature, contains no solvents, and may be applied by brush, trowel, roller coating or silk screening. TRA-BOND 5126 is used for bonding thermally ablative insulation materials to aerodynamic surfaces and meets the Boeing Material Specification BMS 5-126 and similar specifications of other major aerospace manufacturers for high strength, high reliability bonds to many surfaces including phenolic plastics, polyester and epoxy laminates, glass and glass fabrics, hardboard, and to most metal surfaces. Fully cured TRA-BOND 5126 is a tough, durable, dimensionally stable electrical insulator with good low temperature, mechanical, thermal shock, and impact resistance properties coupled with excellent resistance to gases and vapors, petroleum products, solvents and lubricants, water, weather, salt water and salt solutions, mild acids and alkalis, and many other organic and inorganic compounds.Information provided by Tra-Con Inc.
