product introduction

Cellulose acetate butyrate (CAB) serves as an effective binder for both protective and decorative coatings across multiple substrates including metal, wood, textiles, paper, plastics, and leather. As a versatile additive widely adopted in the coatings industry, CAB offers distinct advantages over traditional cellulose acetate (CA), exhibiting solubility not only in strong polar solvents but also in alcohol-based systems.

This polymer demonstrates excellent compatibility with various synthetic resins and high-boiling-point plasticizers, while delivering superior performance characteristics such as:

Resistance to yellowing
Enhanced flexibility and cold resistance
Excellent color retention
Superior flow properties
High hydrolysis resistance
Outstanding transparency

CAB has demonstrated tremendous value in the automotive sector. China AAB Group’s CAB-381-2, CAB-381-20, CAB-551-0.2 are wildly used in Automotive paints and coating, also CAB-381-0.1,CAB-531-1 and CAB-551-0.01 can be used in Automotive Industry.
