ZINC RICH PRIMERS FOR CORROSION PROTECTION - …

Abstract: Various types of zinc-rich coatings are available for corrosion protection. The challenges associated with the proper specification and application of zinc-rich coatings are briefly discussed. The paper then focuses on data from various studies, which quantify the corrosion protection benefits of various types of zinc-rich coatings.

Epoxy Zinc Phosphate - Corrosionpedia

Epoxy zinc phosphate is used to produce epoxy primers and sealers that have a non-porous finish. They are primarily recommended as the first base coat over bare steel. These base coats or epoxy primers are also used over fiberglass, plastic or a black iron phosphate coating. An epoxy zinc phosphate primer can also be used on cracks and dents.

Zinc Rich Primers - Organic & Inorganic Zinc Rich Primers ...

The zinc salts, which invariably form, fill the pores of the primer sealing off the steel substrate from moisture. They also are very flexible when applicating, as top coats don't need to be applied immediately after the primer. We provide both organic and inorganic zinc rich primers. Inorganic primers are typically only spray-applied.

Zinc-rich primer | US Coatings

Zinc primers. Zinc-rich primers offer excellent adhesion properties, as well as galvanic protection for structural steel surfaces. When in contact with structural steel, zinc primers corrode preferentially to the steel, protecting it from damage.[PDF]
