high butyryl content and lower solution viscosity Eastman™ Cellulose Acetate Butyrate (CAB-551-0.2) for Coatings

Short Description:

Product Description:   Eastman Cellulose Acetate Butyrate (CAB-551-0.2) is a cellulose ester with high butyryl content and relatively low molecular weight. It is compatible with numerous cross-linking resins and has a lower solution viscosity. In coatings, Eastman CAB-551-0.2 gives clear films, reduces surface tack and mottling, minimizes cratering, improves flow and thermal reflow, and provides inter coat adhesion and good UV stability. It is useful for durable cross-linked formulations. Its good compatibility with a wide range of curing resin systems and its solubility in a wide variety of solvents and solvent combinations make it useful as an additive in numerous coating compositions. Eastman cellulose esters are based on up to sixty percent cellulose, one of the most abundant natural renewable resources.
