● EPB is an epoxy group introduced into the HTPB molecular chain, which has the advantages of oil resistance, aging resistance, good transparency, low temperature performance, etc. The hydroxyl group at the end of molecular chain and the epoxy group in the molecular chain are reactive groups, and can be cured with a variety of isocyanates and epoxy curing agents.

● The cured polymer has good physical and chemical properties, excellent bonding strength to metal and glass and other non-metallic materials, good dielectric properties, low shrinkage rate, high hardness, stable to alkali and most of the volume, which can greatly improve the mechanical properties, bonding strength and heat resistance of polyurethane materials.

● The polar groups improve the bonding properties of the product with metal and non-metal materials; It can be used in adhesives, sealants, coatings, epoxy resin toughening, polyurethane elastomers, etc.
