Guardian Petrolatum Primer ST

Guardian Petrolatum Primer ST is a surface-conditioning primer designed for use with the Guardian Petrolatum System to support long-term corrosion protection across pipeline, marine, and industrial applications. Formulated to penetrate surface irregularities and displace moisture, the primer improves adhesion between the substrate and subsequent petrolatum wrapping layers. It is suitable for use on hand-prepared steel surfaces and complex geometries including welds, flanges, valves, and fittings. Designed for above-ground, below-ground, and splash zone environments, Guardian Petrolatum Primer forms an important part of a complete corrosion protection wrapping system.
