Bio-based ethyl acetate
CAS 141-78-6
Bio-based ethyl acetate:
ASTROBIO™ AC, sample on request.
ASTROBIO™ AC is pure ethyl acetate (CAS 141-78-6): the ethyl ester of natural acetic acid, miscible in many organic solvents, with a low boiling point, a fast evaporation rate and great solvency power. A valid alternative to many fossil solvents in coatings, lacquers, paints, varnishes and inks. For urethane systems, the NV grades are hydroxyl free.
