CLEARCO ZINC RICH PRIMER
90% + Zinc in the Dry Film 鈥? Equivalent of Hot Dip Galvanize for Corrosion Protection
Clearco Zinc Rich Primer is an organic zinc rich primer for steel and ferrous metals that
combines the resistance properties of epoxy and the galvanic protection of zinc. This
is a pure zinc epoxy base one-package primer.
This high performance epoxy compound fuses zinc to the metal substrate and
protects against corrosion equal to Hot Dip Galvanizing. Clearco Zinc Rich Primer is
self-healing, and prevents creepage even when the surface is penetrated or scratched.
Uses include: Coastal and marine exposures, refineries, water treatment plants, chemical
plants, pulp and paper facilities and applications including touch up and repair of
inorganic zinc coatings and galvanic metal.
Topcoating: After curing, it may be coated with conventional primers and finishes such as
epoxy, coal tar epoxy, vinyls, phenolics, urethanes, acrylics & chlorinated rubber

SURFACE PREPARATION
New Steel: Surface must be dry and free of contamination. Remove all weld splatter and grind all rough welds and
sharp edges to a smooth contour. For severe exposure (immersion, chemical etc) near-white blast clean per SSPC SP
10-63T. For other exposures, blast clean per SSPC SP 6-63 to a maximum profile of 1.5 mils.
Previously Painted Surfaces: Must be free of oil, grease or other contamination. For best results, spot blast exposed
areas to be primed. Power tool brushings may be used for minor touch-up. Power tool brushings may be used for
minor touch-up.

Double lap all welds, seams, corners & edges to
ensure film thickness. Make even parallel passes
with 50% overlap to provide uniformity.
FIRST AID
If swallowed, DO NOT induce vomiting. Contact
physician immediately. In case of eye contact, flush
immediately with clear water for a minimum of 15
minutes and seek medical attention. For skin contact,
wash with soap and water. If overcome by vapors,
remove to fresh air.
