CAB

There is a wide range of butyryl, acetyl, and hydroxyl levels available in Eastman CABs and, consequently, a wide range of properties. The selection of a CAB should be based on the requirements of the application.

• Low butyryl level: Toughness and Heat Resistance.
• Medium butyryl level: Solubility and compatibility with resins and plasticizers.
• High butyryl level: Reduced dry-to-touch time and cratering. For crosslinked finishes.
• High hydroxyl levels : Alcohol solubility. For curing finishes.
• Low molecular weight (low viscosity): Additives/reactive intermediates. For curing finishes.

CAP

CAP properties are intermediate between CA and CAB. They resemble CA in many performance properties and are similar to CAB in solubility and compatibility.

CAPs with high hydroxyl content are soluble in in alcohol-water mixtures. They provide low odor, nonyellowing characteristics, fast solvent release, and good adhesion to plastic films and paper.

CA

The solution grade CAs only differ in molecular weight; the chemical compositions of the cellulose acetates suitable for coatings are the same. The selection of these esters therefore depends on the viscosity that can be used.
