UV Curable Epoxy

Formulated for demanding bonding, sealing, and coating applications, the one component, no mix UV16 epoxy from Master Bond cures in one minute or less at room temperature with commercial UV light sources. It is uninhibited by oxygen and does not release any solvents or volatiles during curing. The epoxy cures in thicknesses up to 3.175mm and has a 2 to 3% shrinkage rate. Once cured it delivers a tensile strength exceeding 282.7 bars and a Shore D hardness over 75. Post curing at 90 to 125 °C for 30 minutes gives the adhesive a glass transition temperature of 135 °C and enhances its chemical resistance. Especially resistant against acids and solvents, the epoxy has a volume resistivity of 1.6x109MΩ-cm and excellent insulation properties up to 149°C. It has a viscosity of 200 to 400 cps and adheres well to a wide array of substrates, including plastics, glass, and many metals. A higher viscosity version, UV16TK, is also available.
