PLHL52-3 Winter-Grade Epoxy Coal Tar Bitumen Coating Description

Overview

PLHL52-3 Winter-Grade Epoxy Coal Tar Bitumen Coating is a two-component winter-grade epoxy coal tar bitumen coating designed to cure under low-temperature conditions. This coating is used for corrosion protection of steel and concrete in severe corrosive environments and is suitable for the external anti-corrosion of buried pipelines.

It is composed of epoxy resin, coal tar pitch, anti-rust pigments, solvent, additives, catalyst, and a fast-drying curing agent, and is supplied as Part A and Part B.

Key Benefits

  • Designed to cure under low-temperature conditions.

  • Suitable for corrosion protection of steel and concrete.

  • Suitable for severe corrosive environments.

  • Suitable for external anti-corrosion of buried pipelines.

  • Volume solids: ≥75%.

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

Typical application areas

  • Steel structures in severe corrosive environments

  • Concrete structures in severe corrosive environments

  • External anti-corrosion of buried pipelines
