Overview
CAB-381-20 BP is a mixed cellulose ester with moderate butyrate content. It is designed to have a lower solution viscosity than standard CAB-381-20 making it especially useful in coating applications that require a higher solids content. Coatings made with CAB-381-20BP have excellent UV resistance, ideal pigment orientation, high gloss, and are remarkably durable. CAB-381-20BP can also be used as an additive to decrease surface defects in a coating by improving the flow and leveling. It is also commonly used as replacement for nitrocellulose in wood coatings and nail polish due to the superior UV stability and safety.
