Pentalyn® FC

Pentaerythritol ester of maleic anhydride-modified wood rosin. It is a pale, high softening point, high acid number, thermoplastic resin. It is highly soluble in typical organic solvents as well as in dilute aqueous solutions of alkalies, including ammonia. Promotes high gloss and hardness. It is particlulary suitable for modifying compositions based on alcohol-soluble and water-soluble film formers, to which it contributes high gloss, block resistance, fast solvent release and good adhesion.
