Polyurethanes offer excellent gloss and color characteristics. They are often used to give surfaces a smooth, thin film build that will provide abrasion resistance, good corrosion control and resistance to chemical exposure. They are versatile coatings that can be specifically formulated to cope with a number of different circumstances.


  • High gloss finish
  • Good color retention
  • Customizable based on needs


  • Short pot life
  • Contain potentially harmful isocyanates
  • Will likely require a multiple component system

Common Applications:

Common applications for polyurethanes include use as topcoats for the protection of steel and concrete substrates. This can include on bridges, storage tanks, barges, refineries, petrochemical plants, etc.


Polyurethanes are often used to achieve a smooth, thin film build over the top of a zinc primer and epoxy intermediate coat.
