Waterborne polyurethanes for Effective Corrosion Protection

Durable corrosion protection and low VOC

Waterborne polyurethanes for effective corrosion protection

Architects, designers, and asset owners/managers, like many consumers, prefer to use more environmentally friendly products if they meet their performance expectations. Waterborne polyurethane coatings are an excellent choice for applications requiring light-to-heavy-duty corrosion protection and low-volatile organic compound (VOC) content.

Waterborne PU coatings for long-lasting corrosion protection

One-component (1K) polyurethane (PU) dispersions from Covestro are used in light-to-medium duty applications, while two-component (2K) waterborne PU coatings are ideal for medium-to-heavy-duty applications.    Waterborne polyurethanes are traditionally used when low-VOC content is required. 

 

 

 

 

Waterborne polyurethanes offer:

  • Excellent weather, chemical, abrasion and impact resistance
  • Low VOCs
  • Easy application
  • Good adhesion to steel and other metal surfaces
  • A wide range of raw materials to formulate the correct balance of flexibility and hardness

Our Bayhydrol® 1K water-based PU dispersions  are available for waterborne protective coating formulations suitable for light-to-medium-duty corrosion protection applications.

Our waterborne Bayhydrol® polyols  in conjunction with our Bayhydur® or Desmodur® polyisocyanates are used for 2K waterborne polyurethanes in medium-to-heavy-duty coatings.
