product introduction

CAB is a semi-synthetic polymer material produced through the esterification reaction of cellulose with acetic acid and butyric acid anhydride. It combines the rigidity of cellulose acetate (CA) with the flexibility of butyric acid groups.CAB-551-0.2 and CAB-551-0.01 are wildly used in powder coating industry,exhibiting the following characteristics:

Excellent solubility — soluble in organic solvents such as ketones, esters, and ethers
High transparency and low color — suitable for high-gloss, high-transparency coatings
UV resistance and weatherability — extends the outdoor service life of coatings
Good flow properties and anti-craters — improves the surface quality of the coating film

Application of CAB in powder coatings

1) Improving coating performance

Enhancing flow properties: Reducing surface defects such as orange peel and pinholes, suitable for high-gloss coatings in automotive and home appliance applications
Enhancing adhesion: Promoting bonding between the coating and metal or plastic substrates
Improved weather resistance: UV stability superior to pure acrylic resins, suitable for outdoor powder coatings

(2) Specialty functional coatings

Metal effect powder coatings: CAB can serve as an aluminum powder orienting agent, enhancing metallic luster effects
Low-temperature curing coatings: Reduce curing temperature (down to 120–140°C), saving energy
Antibacterial/anti-fingerprint coatings: CAB has good compatibility with additives such as nano-silver
