Hydrogenated Rosin

Hydrogenated Rosin is one of the dominant varieties of modified rosin with light color, high oxidation resistance and high thermal stability. Conjugated unsaturation of abietic resin acids can be removed through catalytic hydrogenation to overcome the shortcomings of oxidation and color degradation in rosin, is compatible in useful proportions with alkyds, natural and synthetic rubbers, natural resins, ethylcellulose; waxes; plastic polymers, elastomeric polymers, metallic pigments, and many other raw materials. Hydrogenated rosin is widely used in food-grade ester gum, adhesive, synthetic rubber, coating and paint, ink, cosmetic, food industry etc.
