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-551-0.01) has many unique attributes that will serve useful across many different coating application areas. It has the lowest Tg (glass transition temperature) of the CAB portfolio. It also has the second lowest M(n), which helps its compatibility with other coatings components. It is compatible with numerous cross-linking resins and has a lower solution viscosity. In coatings, Eastman CAB-551-0.01 gives clear films, reduces surface tack and mottling, minimizes cratering, improves flow and thermal reflow, and provides inter coat adhesion and good UV stability. 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. When dissolved in appropriate solvents selected for CAB-551-0.01, a clear, colorless solution is produced. It is useful in lacquers for glass, plastic, wire and release coatings and is available in pellet form.
