Tra-Con Tra-Bond 2112 Rigid Epoxy Staking Compound
Categories: Polymer; Adhesive; Thermoset; Epoxy; Filled/Reinforced Thermoset

Material Notes: TRA-BOND 2112 is a thixotropic epoxy system recommended for critical electronic, aerospace and industrial bonding, laminating and reinforcing applications requiring an adhesive with high-fill, non-sag characteristics. This two-part, solvent-free adhesive is easily mixed and used for staking components to printed circuit boards for enhanced mechanical rigidity, and for bonding, laminating and repair applications involving metals, glass, ceramics, wood and many plastics. TRA-BOND 2112 hardens to a tough, enamel-like coating offering good chemical resistance as well as superior physical and mechanical properties. The cured adhesive provides good electrical insulation and resistance to weather, galvanic action, petroleum products and lubricants, alcohol, salts, mild acids and alkalis, and other organic and inorganic compounds.
