Elastic and durable OH-functional polyurethane dispersions for waterborne 2K coatings & 1K stoving systems. Their key property is their similarity to conventional PU coatings so that equal performance can be achieved in some applications.

Their hydroxyl content ranged from 1.5 to 2.5 percent. They are characterized by high hardness, elasticity, excellent abrasion resistance, weather resistance and hydrolysis resistance. They can be used alone or mixed with water-based hydroxyl polyacrylic resin and water-based polyester etc. They mainly be used in 2-pack systems with water-dispersible polyisocyanate crosslinker or be combined with an amino resin to formulate water-dilutable stoving coatings and primers which cure at approx. 100-140℃.

The following are a few of our most common hydroxyl-functional waterborne polyurethane products:
