CorroPipe Zinc Rich Primer

Liquid Galvanizing for Steel

CorroPipe Zinc Rich Primer is a high-solids, polyurethane-based primer/coating combining the best of several corrosion protection technologies: aluminum and micaceous iron oxide (MIOX) barrier protection; the sacrificial protection of zinc; plus corrosion inhibitors. These proven technologies work synergistically within CorroPipe Zinc Rich Primer, allowing this product to outperform every other high-performance primer on the market and offering protection equivalent to hot-dip galvanizing.

CorroPipe Zinc Rich Primer is paint-like and very easy to apply by brush, roller or spray. When applied, it polymerizes to form a monolithic film that works like galvanizing to protect any ferrous substrates. It is effective at very low thicknesses (3-4 dry mils) but can easily be applied to higher thicknesses without mud-cracking. Because of its pleasing silver metallic finish and its ability to form a flawless finish on porous substrates, this product is also used on concrete and wood.

This product is sometimes used on its own (two coats recommended) but is more typically teamed up with CorroPipe 1:4 Aliphatic topcoat.

Typical Applications

Where resistance to rust or corrosion undercutting is required and a paint-like format is desired.

Application Summary

CorroPipe Zinc Rich Primer is a ‘Single-Component-Plus-Catalyst’ system. It applies like paint, most commonly with an airless spray gun at pressures in the 2,000 to 2,500 psi range. It has a variable pot life, dependent on catalyst selection (15 minutes to two hours) and is cured to touch within 30 minutes to two hours.
