UV Curable Nanosilica Filled Epoxy

Thursday, August 06, 2009
The UV22 is a nanosilica reinforced UV curable epoxy system. The nano-sized filler (<50 nm) gives the cured system abrasion resistance, optical clarity, low shrinkage and physical strength properties at a viscosity of 4,000 cps. The tensile strength of the cured epoxy is greater than 4,600 psi and its tensile modulus is greater than 500,000 psi.
It cures rapidly upon exposure to UV light at room temperatures. This single component has a low coefficient of thermal expansion and is a superior electrical insulator. Post curing UV22 enhances its temperature and chemical resistance properties. For example, post curing at 90-125° C for 30 minutes will give it a glass transition temperature of greater than 120° C. It has a service temperature range of -60 to +300°F.
