OptiCLEAR Liquid Encapsulant
OptiCLEAR is a transparent liquid encapsulant. These 100% solids,
no odor epoxies, can be UV and/or thermally cured for maximum
process flexibility. They are engineered to work well when applied in
thick or thin films, available in several viscosity ranges. OptiCLEAR
products are excellent alternatives to acrylic encapsulants.
