Waterborne Polyurethanes for Protective Marine Coatings

Sustainable corrosion protection

Waterborne polyurethanes for protective marine coatings

The marine industry is looking for more sustainable solutions to use in anticorrosion coatings. One-component (1K) waterborne polyurethane (PU) coatings are an ideal choice because they are environmentally friendly and offer high-performance protection.

Sustainable corrosion protection with waterborne polyurethanes

Waterborne marine coating technologies from Covestro are preferred for light-to-medium-duty corrosion protection applications.

In fact, water-based protective marine coating technology has advanced significantly in recent years. Today, 1K waterborne PU coatings offer long-lasting protection with a durable, attractive appearance.

 

 

 

 

Waterborne polyurethanes:

  • Are easy to apply
  • Offer good adhesion to steel and other metal surfaces
  • Provide excellent weather, chemical, abrasion and impact resistance
  • Exhibit long-lasting color and gloss retention
  • Have good flow and leveling characteristics
  • Have tunable hard and soft segments for control of their flexibility/stiffness
  • Feature low volatile organic compound (VOC) contents

Our Bayhydrol® 1K water-based PU dispersions are available for the formulation of waterborne marine coatings that can be air dried.

Two-component (2K) waterborne PU systems are also suitable for marine corrosion protection applications. Our Desmophen® polyols and Desmodur® polyisocyanates  are used in formulation of these waterborne protective marine coatings.
