PLH53-35 Epoxy Zinc Primer (C6-Modified) Descriotion

Overview
Two-component epoxy zinc primer modified with special C6-element material and cured with a polyamide hardener.
It is intended for cathodic-protection priming and use in industrial anti-corrosion coating systems, including localized repair of inorganic zinc-rich primer coatings.

Composition
Epoxy resin, ultrafine zinc powder, anti-settling agent, toughening agent, solvent; modified with special C6-element material; polyamide curing agent; supplied as Part A and Part B.

Typical uses

  • Ship repair/building, bridges, petrochemical facilities, steel structures, offshore platforms, underwater steel structures, pipelines, and oil tanks.

  • Used as a cathodic-protection primer and for localized repair of inorganic zinc-rich primer coatings.
