Atom Adhesives AA-BOND 2103 Epoxy Adhesive
Categories: Polymer; Adhesive; Thermoset; Epoxy; Epoxy Adhesive

Material Notes: AA-BOND 2103 is a clear, near transparent, medium viscosity epoxy adhesive formulation developed for rigid laminating, sealing and bonding applications where the combination of good wetting and improved mechanical electrical properties is required. AA-BOND 2103 is two-part liquid epoxy adhesive contains no solvents and is easy to mix, use and apply at room temperature. AA-BOND 2103 develops strong, rigid, high performance bonds to itself and to ceramics, glass and glass fabrics, metals, laminates and other composite materials, forestry and masonry products, and to most rigid plastics. AA-BOND 2103 is an effective electrical insulator, and further provides excellent resistance to weather, galvanic action, vapors, JP4 fuel, gasoline, lubricants and other petroleum products, mild acids and alkalis, salts, and other organic and inorganic compounds.
