PT-522 Yellow Primer is a general purpose zinc chromate primer.
PT-522 yellow primer is a rust inhibitive alkyd primer intended for use over metals that are bare, scuffed, sanded, lightly rusted, abrasive blast and/or previously painted surfaces. It shows excellent anti corrosion properties. PT-522 chemically etches into the surface to provide exceptional adhesion and durability. Moisture in the air causes the zinc chromate to react with the metal surface, and it forms a passive film that prevents corrosion. In addition to metals, PT-522 may be applied to wood, composite and concrete surfaces. PT-522 is not resistant to all solvents, i.e. MEK and Acetone.
PT-522 is most commonly available in Yellow and Green, but can be provided in red.
