CA-398-3 is the lowest viscosity grade of the cellulose acetate range. It is used as additive in protective coatings for electronics, adhesives and plastic products.
CA-398-3 provides performance benefits in solvent- and grease-resistant coatings for textile, wire and paper products, barrier and release coatings for adhesives, protective coatings for plastic items and membrane material. Cellulose acetates are only 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.
