Master Bond Polymer System EP37-2 is a low viscosity, optically clear two component epoxy resin system designed for flexible high performance casting, coating and adhesive applications. It is prepared for use by mixing the two components in a non-critical convenient one-to-one mix ratio, weight or volume, and can be readily cured to a tough, flexible, optically clear elastomeric solid at either ambient or more rapidly at elevated temperatures.

The Master Bond EP37-2 epoxy resin system is successfully employed as an optically clear encapsulant with excellent resistance to thermal shock; a sealant with outstanding adhesion characteristics that will withstand wide variations in substrate expansion and contraction without cracking or failing; coatings, that are clear, flexible and impact resistant and durable flexible adhesives for bonding both similar and dissimilar substrates.
