Very Low Viscosity, Optically Clear, Two Component Bonding, Sealing, Coating and Casting Compound 11 Mar 2021 Master Bond Polymer System EP30LV-1 is an ultra low viscosity, two component epoxy system for high performance bonding, coating, sealing, potting and encapsulation. It readily cures at room temperature or more rapidly at elevated temperatures, and has a five to one mix ratio by weight. This adhesive is 100% reactive and does not contain any solvents or diluents. EP30LV-1 has outstanding physical strength properties along with excellent electrical insulation characteristics. This highly dimensionally stable system has very low shrinkage after cure, less than 0.001 in/in. EP30LV-1 possesses very good optical clarity along with superior light transmission when compared to many other epoxies.
