CA-398-10 is a medium viscosity cellulose acetate. It gives high strength and excellent chemical resistance in coatings and adhesives.


44lb Bag



Product Overview

CA-398-10 offers excellent chemical resistant, a high glass transition temperatures and produce tough and hard films.  Cellulose acetates are soluble in strong solvents like acetone, methyl ethyl ketone, and ethyl acetate. They are compatible with plasticizers such as dimethyl phthalate or triacetin. The melting point and harness are relatively high. In membranes cellulose acetates (CA) provide strong, clear, chlorine resistant films.
