Tra-Con Tra-Bond 2111 Rigid Epoxy Staking Compound
Categories: Polymer; Adhesive; Thermoset; Epoxy

Material Notes: TRA-BOND 2111 is a thixotropic epoxy resin and hardener formulation developed for industrial adhesive, staking, laminating, repair and manufacturing applications where long pot-life, good wetting, non-sag, non-drip and improved impact strength properties are required. This easy-to-use two part adhesive system contains no volatile solvents, readily cures at room temperature, and bonds to most materials including glass and glass fabrics, ceramics, wood, leather, most metals, and many plastics. Fully cured TRA-BOND 2111 is strong, tough, resilient, has superior mechanical impact and thermal shock resistance characteristics, and is also highly resistant to weather, water, gases and vapors, most petroleum products and fuels, salts, mild acids and alkalis, and many other organic and inorganic compounds.
