Hybrid polymers are the polymers easily modified with various types of resin, like acrylic acid and epoxy resin. Silyl Terminated Polyether (STPE) and Silylated Polyurethane Resin(SPUR) are two of the major types widely used in gap filling and waterproof sealing in building and construction. Everlight Chemical’s Eversorb® HP Series is to improve UV and heat resistance of hybrid polymers, protecting polymers from yellowing, cracking and the loss of physical properties.properties. To enable a longer and effective life cycle of sealants in outdoor use, Eversorb® HP series is a smart solution for UV light & heat stability.
