CB-8950 modified rosin resin is a maleic acid-modified rosin ester resin. It has the characteristics of being soluble in alcohol solvents, fast drying, high gloss, and good adhesion. It is mainly used in gravure printing inks and glazing oils. CB-8950 can also be dissolved and neutralized with alcohol solvents and ammonia or organic amines to form a water-soluble resin liquid, which can be used in water-based ink systems.
