HBPA is mainly used in the manufacture of epoxy resin, polycarbonate, acrylic resin, unsaturated resin, with characteristics of thermal stability, chemical stability and weather resistance. Furthermore, HBPA has excellent electrical performance, low viscosity and good processing usability etc. Compare to Bisphenol A type epoxy resin, HBPA type epoxy resin can solve the application limitation of poor weather resistance, easy to aging and air-slake.
