UV-curing adhesive

    June 26, 2009
    Nanosilica additions lend strength and abrasion resistance to a UV-curing adhesive.
    UV22 is a UV-curable epoxy reinforced with silica particles <50nm in diameter. The reinforcement increases abrasion resistance, improves optical clarity, reduces shrinkage, and boosts strength. The resin's viscosity is 4,000 cps.

    The single-component adhesive cures rapidly when exposed to UV light without heat. The material has a low coefficient of thermal expansion and is electrically insulative. The cured adhesive resists most chemicals, and withstands exposure to solvents, acids, and bases after postcure. Cured tensile strength is >4,600 psi, and cured tensile modulus is >500 ksi.

    UV22 operates between -60 and 300°F. It comes in syringe applicators. A dual-cure version that cures with UV or heat is also available.
