PLHS-1 Epoxy Polyurethane Heavy-Duty Anti-Corrosion Coating Description

Overview

PLHS-1 Epoxy Polyurethane Heavy-Duty Anti-Corrosion Coating is a two-component heavy-duty anti-corrosion coating based on epoxy and polyurethane chemistry for steel structures, pipelines, tanks, bridges, and wharves.
This coating is used for corrosion protection on steel structures, gas pipelines, chemical facilities and pipelines, oil tanks and vessels, bridges and wharves, gas holders, motors and electrical equipment, aluminium alloy, and cement substrates.

It is composed of polyurethane prepolymer, epoxy resin, special additives, pigments, solvent, and auxiliaries.

Key Benefits

  • Based on epoxy and polyurethane chemistry.

  • Suitable for steel structures, pipelines, tanks, bridges, and wharves.

  • Suitable for gas holders, motors and electrical equipment.

  • Suitable for aluminium alloy and cement substrates.

  • Medium resistance: 60 d no blistering, no peeling, no rusting (5% acid/alkali/salt).

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