Product description

Eastman Cellulose Acetate (CA-398-3) is one of the lower viscosity solution grades of cellulose acetate. The average ASTM viscosity of CA-398-3 is 3 seconds. Eastman CA-398-3 is supplied in the form of a fine, dry, free-flowing powder. This multipurpose rheology enhancer provides high strength and good resistance to ultraviolet light, heat, oils and greases. Useful in lacquers for glass, plastic, wire and release coatings. It may be blended with appropriate solvents, plasticizers, and other modifying resins to formulate coatings for paper, glass, plastic, wire screen, and electrical wiring. When dissolved in appropriate solvents selected for CA-398-3, a clear, colorless solution is produced.

Eastman CA-398-3 is based on cellulose, one of the most abundant natural renewable resources, from trees harvested from sustainably managed forests. The calculated approximate bio-content value of 55% for Eastman CA-398-3 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.
