Polymerized Rosin

Polymerized rosin is a pale, acidic, thermoplastic, high softening point resin. It is composed predominately of dimeric acids derived from rosin with lesser amounts of monomeric resin acids and neutral materials of rosin origin. It has high resistance to oxidation and does not crystallize from solutions or from solid compositions. It is compatible with many natural and synthetic film formers and rubbers. Being an acidic resin, it reacts readily with polyalcohols to yield high melting derivatives.

Applications:

Suitable for inks, adhesives, paints, coatings, fluxes, synthetic resins, etc.

Specification:
