Overview
CAB-381-2 BP is designed to provide a lower solution viscosity than standard CAB-381-2. This allows for lower viscosity while still keeping solids content relatively high. CAB-381-2 BP is compatible with most common solvents, plasticizers and resins and as such is a useful tool for formulators looking to make high performance coatings. Coatings that incorporate CAB-381-2 BP have better flow and leveling, fewer surface defects, better pigment orientation, and improved UV stability.
