The UV22 nanosilica-reinforced, UV curable epoxy offers a combination of properties not available in conventional epoxy systems. Features of the nano-sized filler (<50 nm) include abrasion resistance, optical clarity, low shrinkage, above-average physical strength, low viscosity of 4,000 cps, low coefficient of thermal expansion, and chemical resistance. Tensile strength of the cured epoxy is >4,600 psi and its tensile modulus is > 500,000 psi. UV22 cures rapidly at room temperature in UV light. The single-component epoxy requires no mixing, is environmentally friendly, solvent-free, and not oxygen inhibited.
