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 reinforcements resulting in fast curing and a tack-free surface. It is recommended for moderate chemical resistance applications. At moderate temperatures, the resin has good resistance to water, acids (dilute to medium concentrations), weak bases, and good resistance to petroleum solvents like vessels, tank linings, ducting fume hoods, and many other applications requiring good chemical resistance and superior mechanical strength compared to Ortho-phthalates.
