PLX06 Vinyl Phosphating Primer Description

Overview

PLX06 Vinyl Phosphating Primer is a two-component vinyl phosphating primer formulated to form a coating with chemical adhesion on non-ferrous/light metal surfaces and improve adhesion of subsequent coatings.

The product is formulated with polyvinyl butyral resin, anti-rust pigments, passivator, solvent, additives, and an acidified curing agent. It is used for phosphating treatment on galvanized steel and aluminum and, when used with epoxy anti-rust coatings, it is stated to enhance salt spray corrosion resistance and moisture resistance of the coating film.

Key Benefits

  • Forms chemical adhesion on non-ferrous and light metal surfaces

  • Improves adhesion of subsequent coatings

  • Suitable for phosphating treatment on galvanized steel and aluminum

  • Can be used with epoxy anti-rust coatings

  • Stated to enhance salt spray corrosion resistance when used with epoxy anti-rust coatings

  • Stated to enhance moisture resistance when used with epoxy anti-rust coatings

This primer is suitable for surface treatment and adhesion improvement on light metal substrates in coating systems.

Typical application areas

  • Galvanized steel

  • Aluminum

  • Other light metal substrates

  • Projects requiring improved intercoat adhesion of subsequent coatings
