Automotive OEM/Refinish

CABs are especially useful in coatings for structural aluminum and foil, stainless steel, chromium, brass, silver, and tin where protection of the metal surface and maintenance of the metallic luster are desired. By appropriate selection of modifying resins, butyrate based systems may be formulated into clear or pigmented coatings that have good adhesion to metallic surface and that are resistant to salt, fog, oxygen, and other tarnishing and corroding elements.

A small amount of polyester resin combined with CAB produces tough, flexible films for metal protection. Curing coatings based on CAB in combination with polyester resins and amino resins have good chemical resistance. Low-viscosity grade Eastman CAB-381 esters are widely compatible with modifying resins, have high tolerance for lacquer diluents, and are commonly used in clear coatings for metal.

The outstanding weather resistance of thermoplastic acrylic resins is complemented by CAB to provide superior original and refinish automotive coatings. The use of CAB in pigmented acrylic lacquers improves sprayability, flow properties, and resistance to solvent crazing, and provides better orientation of metal pigment.

Adding CAB in the basecoat provides improved metal flake orientation and resistance to redissolve from the topcoat solvents.
