Polyurethane anti-corrosion coatings are widely used as high-performance topcoats in industrial protection systems.
They provide excellent weather resistance, color retention, mechanical strength, and long-term durability for steel structures and industrial equipment exposed to outdoor or harsh environments.
Polyurethane coatings are commonly applied over epoxy primers or intermediate coatings to form a complete corrosion protection system.
Key Performance Advantages of Polyurethane Coatings
Excellent UV and weather resistance
High gloss and long-lasting color stability
Strong abrasion and impact resistance
Good flexibility and adhesion to epoxy layers
Typical Applications
Steel structure topcoats
Industrial plants and workshops
Machinery and equipment surfaces
Bridges and infrastructure
Storage tanks and pipelines (external)
Recommended Polyurethane Coating Systems
Polyurethane as a Protective Topcoat System
In most industrial corrosion protection systems, polyurethane coatings are used as the final topcoat, providing weather resistance and surface protection while enhancing the overall durability of the system.
Typical system structure:
Epoxy or zinc-rich primer
Epoxy intermediate coating
Polyurethane topcoat
