CAB-381-20 CELLULOSE ACETATE BUTYRATE is a cellulose ester with high butyryl content and high viscosity. Other than a higher viscosity and higher molecular weight, this cellulose ester shares the same general characteristics as CAB-381-0.1. CAB-381-0.5. CAB-381-20 offers a combination of solubility and compatibility, moisture resistance, excellent surface hardness, and good film strength. CAB-381-20 is supplied as a dry, free-flowing powder.

CAB-551-0.01 CELLULOSE ACETATE BUTYRATE is a cellulose ester with high butyryl content and low viscosity, which significantly affects it solubility and compatibility. CAB-551-0.01 is soluble in styrene and methyl methacrylate monomers and will tolerate more aliphatic and aromatic hydrocarbon diluent than higher viscosity materials. The solubility of CAB-551-0.01 in alcohol/aromatic hydrocarbon mixtures offers an economic advantage and permits the choice of a wide range of solvents and solvent combinations. It also offers improved compatibility with various coating resins. CAB-551-0.01 is a dry, white free flowing powder convenient to handle.

CAB-381-0.1 CELLULOSE ACETATE BUTYRATE 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 is 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.

CAB-551-0.2 CELLULOSE ACETATE BUTYRATE 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, CAB-551-0.2 gives clear films, reduces surface tack and mottling, minimizes cratering, improves flow and thermal reflow, and provides intercoat 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.
