Polymerized gum rosin with low odor, dark color and high softening point can partially substitute maleic resins. Offers some advantages due to its high solution viscosity. Found to be completely soluble in aromatic hydrocarbons, ethyl acetate and most part of ketones, slightly soluble in alcohols, aliphatic hydrocarbons and insoluble in water. Recommended applications include primers and inks.
Partially hydrogenated rosin is made of partially hydrogenated natural gum rosin. Hydrogenation process gives it outstanding properties such as low-stable color, oxidation and aging resistance. Widely used as raw material for the manufacture of synthetic resins, metal resinates and other products, obtaining higher qualities than using gum, tall oil or wood rosin. It is compatible in useful proportions with alkyds, natural and synthetic rubbers, natural resins, ethylcellulose, waxes and many other raw materials. Recommended to be used in the manufacture of synthetic resins, metallic resonates and coatings.
