What is vinyl wash primer.

Vinyl wash primer description. A two component pre treatment bonding primer which will assure adhesion to almost any non ferrous surface aluminum copper brass magnesium and ceramic tile ferrous metals and zinc coated steel. A wash primer or self etching primer uses a metal conditioner to neutralize surface oxides and hydroxides as well as etch the galvanized surface to provide a surface suitable for painting. Part a contains an alcohol solution of polyvinyl butyral resin pigmented with zinc chromate while part b is the.

Traditionally wash primers come as a two pack product and are mixed just prior to use. It is a reactive primer that etches the surface and provides a paintable coating which readily accepts archco linings such as archco 436. The wash primer is applied using a paint spray gun and the film thickness is usually 0 3 0 5 mils. It also contains a corrosion inhibitor such as zinc chromate.

What makes it unique is that there is phosphoric acid in the coating. Archco vinyl wash primer provides superior adhesion to aluminum and galvanized surfaces. It is used as a first coat on metal surfaces and has anticorrosion properties making it a prerequisite or pretreatment before any coating application. A wash primer is a synthetic primer that usually contains zinc chromate or phosphoric acid.

Compatible with a wide range of solvent based topcoats.
