EASTMAN™ CELLULOSE ACETATE BUTYRATE (CAB-531-1)

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 that requires lower plasticizer modification than the Eastman CAB-381 esters. When CAB-531-1 is dissolved in appropriate solvents, a clear, colorless solution is produced. Eastman CAB-531-1 is based on cellulose, one of the most abundant natural renewable resources. The calculated approximate bio-content value of 38% for Eastman CAB-531-1 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.

BUTVAR B-79

Butvar® B-79 is a thermoplastic, polyvinyl butyral resin which offers a unique combination of properties for coating or adhesive applications. The use or addition of polyvinyl butyral to a system imparts adhesion, toughness, and flexibility. PVB retains the clarity of the coating and offers reactive hydroxyl sites for crosslinking with thermoset systems. The broad solubility range of Butvar® B-79 allows it to be formulated into many applications.

Luna-mer 553-A

Luna-mer 553-A is an improved β-hydroxyalkylamide crosslinker, used to formulate exterior-durable carboxylic polyester powder coatings. Luna-mer 553-A provides a lower-yellowing, more colourstable coating, and therefore is most suitable for use in direct-fired gas ovens.
