Polyurethane Dispersions

Polyurethane dispersions are polyurethane (PU) polymers that are dispersed predominately in water, rather than a solvent. Solvents have historically been used as typical PUs are not stable in water (producing urea and carbon dioxide), but recently environmental factors have dictated the removal of solvents from PU dispersion systems. 

Producing PU resins and subsequent disperions that are stable in water requires certain technological steps. Through intensive research this process is now more viable than before. 

Polyurethane dispersions are used as binders in various construction and coatings applications, such as industrial, floor, wood, automotive, and concrete coatings. Adhesvies also can contain PU dispersions. Almost all PU dispersion applications have high UV and water resistant characteristics.
