Good Resistance And Lower Plasticizer Modification Cellulose Acetate Butyrate Powder CAB 531 For Coatings

Short Description:

Product Description

Eastman Cellulose Acetate Butyrate (CAB-531-1) is a cellulose ester with a higher butyryl level than Eastman CAB-381 type esters. Tough films with good resistance to marring and weathering are possible through combinations of cellulose acetate butyrate with thermoplastic acrylic resins.
Eastman CAB-531-1 and CAB-381 esters are similar in hydroxyl content and solubility
characteristics, both being soluble in a wide range of solvents. Eastman CAB-531-1 is a more flexible resin requiring lower plasticizer modification than the Eastman CAB-381 esters.
