SYLOID® AQ 880 silicais an additive for premium performance coating, especially for wood. It is a modified matting agent that enables the formulation of more environmentally friendly waterborne wood coatings with high chemical resistance and transparency that produce natural-looking, deep matte finishes on wood furniture, cabinets, and floors. Unlike typical silica matting agents, Grace’s SYLOID® AQ silicas have unique properties that achieve a highly matted surface with excellent chemical resistance, excellent clarity, and good scratch and metal marking resistance. In addition, SYLOID® AQ silicas are easier to disperse and produce less dusting than typical silica matting agent.

EASTMAN™ CELLULOSE ACETATE BUTYRATE (CAB-381-0.1) is a cellulose ester with medium butyryl content and low viscosity. It was designed for use where low-application viscosities at relatively high solids levels are needed. It is soluble in a wide range of solvents and compatible with many other resins. It will also tolerate the use of solvent blends currently exempt from certain air pollution regulations. When CAB-381-0.1 is dissolved in appropriate solvents a clear, colorless solution is produced. It is supplied as a dry, free-flowing powder.

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.
