ISO Resin is a medium viscosity, medium reactive polyester resin based on Isophthalic acid and superior glycols. It exhibits good mechanical and electrical properties together with good chemical resistance compared to general-purpose resins. ISO Resin rapidly wets the surface of glass fiber in the form of cloth mat or chopped fiber to produce laminates and moldings.
