Tra-Con Tra-Bond 2143D Medium Viscosity Polyamide Epoxy Adhesive
Categories: Polymer; Adhesive; Thermoset; Epoxy

Material Notes: TRA-BOND 2143D is a medium viscosity adhesive recommended for industrial bonding and sealing applications where toughness, impact resistance, and superior mechanical properties are required. This two-part adhesive is easily mixed and cured at room temperature, and develops strong bonds to most clean, dry material surfaces including most metals, rigid plastics, glass, ceramics, leather, rubber, wood and concrete. Fully cured TRA-BOND 2143D bonds offer good low- temperature electrical, mechanical, and impact resistant properties, superior thermal shock resistance, low permeability to gases and vapors, good dimensional stability, and resistance to water, weather, oxygen and ozone, most petroleum products, mild acids and alkalis, and many other chemicals.
