Cellulose Acetate Butyrate (CAB) for Automotive Paint
Jan 05, 2026CAB is soluble not only in highly polar solvents but also in alcohol-based systems. It is compatible with a variety of synthetic resins and high-boiling-point plasticizers, and exhibits excellent properties including non-yellowing, flexibility, cold resistance, good color retention, outstanding flow characteristics, hydrolysis resistance, and high transparency.
In coating formulations, CAB significantly improves flow and leveling, eliminates film shrinkage, enhances solvent release, promotes pigment dispersion, improves adhesion, and increases coating hardness. As a key additive, it is extensively used in automotive touch-up paints, motorcycle coatings, metallic finishes, plastic coatings, wood finishes, paper varnishes, fabric coatings, and printing inks.
Resistant to plasticizer migration and easy to polish
