Tra-Con Tra-Bond 2101 General Purpose Epoxy Adhesive
Categories: Polymer; Adhesive; Thermoset; Epoxy

Material Notes: TRA-BOND 2101 is a medium viscosity epoxy formulation recommended for laminating, bonding, repair and other adhesive applications where the combination of its superior structural, mechanical and electrical performance properties are required. This two-part adhesive easily mixes and cures at room temperature, and develops strong, durable, tough bonds to most clean, dry material surfaces - including metals, ceramics, glass and glass fabrics, wood leather, and many rigid plastics. The fully cured TRA-BOND 2101 bonds are good electrical insulators which also provide excellent resistance to weather, galvanic action, many mild acids and alkalis, salt solution, petroleum solvents, lubricating oil, gasoline, jet fuels, alcohol, and many other organic and inorganic materials.
