Product description
Eastman Cellulose Acetate Butyrate (CAB-551-0.2) is a cellulose ester with high butyryl content and low molecular weight, offering compatibility with numerous cross-linking resins and lower solution viscosity.
It provides clear films, reduces surface tack and mottling, minimizes cratering, improves flow and thermal reflow, and ensures inter-coat adhesion and UV stability.
Useful for durable cross-linked formulations, it dissolves in various solvents to produce a clear, colorless solution. Derived from sustainably managed forests, it has an estimated bio-content value of 37%. For food contact applications, refer to Eastman CAB-551-0.2, Food Contact.
