Tra-Con Tra-Bond 2126 Black Opaque Epoxy Adhesive
Categories: Polymer; Adhesive; Thermoset; Epoxy

Material Notes: TRA-BOND 2126 is recommended for those modern photographic, industrial, and laboratory bonding and laminating applications where an easy-to-use, black (opaque) epoxy adhesive system with high performance structural, mechanical and electrical properties is required. This two-part smooth paste thixotropic epoxy formulation contains no solvents and is easy to handle as it readily mixes and cures at room temperature. It bonds strongly to itself and to most materials (including glass and glass fabrics, ceramics, wood, leather, metals and many plastics), exhibits low shrinkage during cure, and has excellent dimensional stability over a wide temperature range. Fully cured TRA-BOND 2126 has good low temperature impact resistance and mechanical properties, and is a most effective electrical insulator. In addition, it is resistant to water, weather, oxygen, ozone, petroleum products, jet fuels, salts, mild acids and alkalis, and many organic and inorganic compounds.
