HETRON 197P Polyester Resin
HETRON 197 P resin is a low viscosity, thixotropic, promoted, halogenated, flame retardant(“) polyester
resin.
– Excellent corrosion resistance to acidic and other oxidizing environments
– High heat resistance – gases and vapors to 177 C (350 F)
– Excellent strength retention at elevated temperatures
– Good flame retardancy – Has met ASTM E-84 Class II rating with addition of 5% antimony trioxide
APPLICATIONS AND _HETRON 197 P resin is recommended for corrosion resistant fiberglass reinforced plastic (FRP)
USE equipment. Applications include filament wound and hand lay-up tanks, pipes, pumps, stacks, scrubbers
and other equipment handling highly corrosive gases, vapors, or liquids.
HETRON 197-3 resin is a non-promoted version of HETRON 197 P.

(1) HETRON polyester resin will burn if provided with a sufficient amount of heat and oxygen. The degree
of flame retardancy of the cured polyester resin is characgterized by the ASTM E-84 tunnel test. This test
is performed under strictly controlled conditions where a flame spread rating is assigned according to
comparisons with test set-point materials. The behavior of the cured composite under these controlled
conditions can vary from an actual fire situation.
