Films prepared from CAB-171-15 offer superior toughness and hardness as compared with films prepared from other mixed esters. Also coatings based on CAB 171-15, which has less solubility and compatibility than the higher butyryl CABs, usually offer excellent resistance to chemicals, oils, and greases.
It is supplied in dry, powder form.
Eastman CAB-171-15 is based on cellulose, one of the most abundant natural renewable resources. The calculated approximate bio-content value of 46% for Eastman CAB 171-15 was determined by using six bio-based carbon atoms per anhyroglucose unit divided by the total number of carbons per anhyroglucose unit. Although the value reported is not specifically measured for bio-carbon, it can be estimated based on typical partition data.
