PLH52-3 Epoxy Glass Flake Topcoat Description

Overview

PLH52-3 Epoxy Glass Flake Topcoat is a two-component epoxy glass flake topcoat with resistance to water and permeation of chemical media, used for long-term heavy-duty corrosion protection. This coating is intended for steel structures and concrete facilities in underwater or humid environments and heavy chemical areas, and it may also be used as an intermediate coat.

It is composed of epoxy resin, glass flakes, pigments, additives, and solvents, with a modified amine curing agent, and is supplied as Part A and Part B.

Key Benefits

  • Resistant to water.

  • Resistant to permeation of chemical media.

  • Suitable for long-term heavy-duty corrosion protection.

  • Suitable for underwater or humid environments.

  • Suitable for heavy chemical areas.

  • Can be used as a topcoat or as an intermediate coat.

This coating is suitable for a wide range of steel and concrete protection projects in industrial and marine environments.

Typical application areas

  • Steel structures in underwater environments.

  • Steel structures in humid environments.

  • Steel structures in heavy chemical areas.

  • Concrete facilities in underwater environments.
