Cellulose Acetate Butyrate(CAB) can serve as a binder for protective and decorative coatings on metals, wood, textiles, fabrics, paper, plastics, and leather. our kabsph series models such as CAB-381-0.1 CAB-381-0.5, CAB-381-2, CAB-381-20, CAB-551-0.2, CAB-551-0.01. Those models are widely used additive in the paint & coating industry.
CAB not only dissolves in highly polar solvents but can even dissolve in alcohol-based solvents. It can be mixed with various synthetic resins and high-boiling-point plasticizers. CAB exhibits characteristics such as non-yellowing, flexibility, cold resistance, good color retention, excellent flow properties, resistance to hydrolysis, and high transparency.
It significantly improves coating flow, eliminates film shrinkage, enhances solvent release, promotes pigment dispersion, improves adhesion, and increases coating hardness. CAB finds extensive application in automotive (touch-up) paints, motorcycle paints, metallic finishes, plastic coatings, wood coatings, paper varnishes, fabric coatings, and printing inks as a coating additive.
The performance value of cellulose acetate butyrate in automotive paint applications.
Enhance the drying speed of paint film；
Enhance ultraviolet resistance, sunlight resistance, light retention and color retention;
Enhance the color brightness and metallic feel of silver powder by directing the silver powder;
Enhance the paint film construction performance and ensure uniform thickness;
Enhance the solvent resistance of automotive paint;
Anti-sag, inhibit shrinkage cavity;
Good wettability to pigment, shortening the grinding time of color paste;
Water white color, good permeability;
Resistant to plasticizer migration and easy to polish.
