Water-White Hydrogenated Rosin

Products & Informations

Water-White Hydrogenated Rosin is one of the dominant varieties of modified rosin with light color, high oxidation resistance and high thermal stability. It is soluble in ketones, esters, hydrocarbons, alcohols and chlorinated solvents and insoluble in water. 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.

This series of products are refined from hydrogenated rosin or high-hydrogenated rosin that are eliminated foreign matter and the coloring radical. Used in solid or liquid solder flux, hot melt adhesive and for the raw material of light-colored rosin resin.


  • used in solid or liquid solder flux, hot melt adhesive and for the raw material of light-colored rosin resin



  • the product can’t be co-stored and mix-carried with spontaneous-articles, strong oxidizer, strong-acid, it can be only handled according to the stipulations of inflammables.
