A new water reducible blocked polyisocyanate (NWRBP) for one component (1K) polyurethane coatings

摘要

A new Water Reducible Blocked Polyisocyanate (NWRBP) was developed that will provide a one component polyurethane baking system with improved properties for typical general product finishing applications. One component polyurethane coatings consisting of a blocked polyisocyanate and formulated with a water reducible hydroxyl functional co-reactant will provide not only excellent storage stability but improved VOC's, HAPs, higher gloss, and improved flow compared to the other water reducible blocked polyisocyanate on the market today. The improved coatings performance is due to less water and a 60
