Organic Zinc Rich Epoxy Primer Anti Corrosion Epoxy Primer
Product OSVX408 Epoxy Organic Zinc Rich Primer is a two component epoxy primer which provides both barrier and sacrificial protection against steel corrosion. Product OSVX408 promotes adhesion, dries rapidly, and can be either shop or field applied.
What is a Zinc Rich Primer? - Definition from Corrosionpedia
A zinc rich primer is a chemical substance that contains high concentrations of the silver-white metal zinc. Zinc rich primers are used by many industries as a preparatory coating to protect iron or steel substrates against corrosion.[PDF]
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 CLAD 3100 is a two-package, waterborne, inorganic zinc pre-construction primer designed to provide excellent welding and weathering properties. Recommended Usage Shipbuilding
High Performance - Rust-O-Zinc Organic Zinc Primer
Rust-O-Zinc Organic Zinc Rich Primer is a three component, polyamide converted epoxy rich coating designed to provide cathodic protection to abrasive blasted steel through the sacrificial action of pure metallic zinc. It provides maximum corrosion protection from severe industrial or marine exposures.

Zinc Rich Epoxy Primer Cost Reduction Initiative 4 Proposal: “Zinc rich epoxy primer with extended overcoat window may be applied, unless otherwise specifically prohibited, as the first coat of epoxy primer in lieu of other epoxy primers” Zinc Rich Primer Eliminates Abrading Requirement Abrade Blast Prime Recoat Clean Affordability Factors:
A two component, zinc-rich epoxy primer, Interzinc 388 is designed to give maximum protection as part of an anticorrosive coating system for aggressive environments. Containing more that 75% zinc, Interzinc 388 conforms to HG/T3668 and is ideal for both maintenance and new construction situations.
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]
Zinc Rich Coatings In Immersion Service, where to use …
• Zinc, under most conditions, is more active than carbon steel and will actively keep carbon steel protected from corrosion provided: 1. There is intimate contact between the zinc and carbon steel. 2. Free zinc available to sacrifice itself. • Zinc is somewhat self healing and will bridge small gaps of …
Inorganic vs. Organic Zinc Rich Primers: What's the ...
Inorganic zinc-rich coatings generally consist of a silicate binder whereas organic zinc-rich coatings can use a wide array of binders including epoxy, polyurethane, and alkyd, etc. Because of the differences in the binders, the performance of inorganic zinc-rich primers versus organic zinc-rich primers varies.[PDF]
