Undercoat Primer


• PPG PR143 epoxy primer

An epoxy primer developed for the internal and external protection of aircraft to undercoat powder coating or painted surfaces. The strontium chromate component provides long term corrosion inhibition and fully cured PR143 possesses excellent resistance to aircraft fluids such as phosphate ester hydraulic oil. The superior water resistance and adhesion characteristics offer a significant advantage over conventional epoxy primers.
