Introduction
M13035 | Rosin Modified Maleic Resin is an irregular transparent, light color solid, getting from esterification of maleic rosin adduct and polyols.
Properties
It can dissolve in ester, non-alcohol solvents (toluene, xylene, butyl acetate, ), turpentine oil, insoluble in alcoholic solvents; partially soluble in petroleum products; mix well with plant oils; light color; resistant to yellowing; heat resistant; good adhesion power.
Applications
For improving of paint films in hardness, glossiness, rubbing property for polyesters, nitrocellulose and PU paints.

Ester Gum is a glycerol ester of gum rosin with low odor and low acid value, especially applicable to chewing/bubble gum base, beverages and flavors. It is also used as a resin modifier for film formers, elastomers, and waxes, and in various adhesives, inks, and protective coating compositions where minimum odor is a requirement.
Gum rosin or refined gum rosin is a kind of natural resin, mainly composed of various kinds of resin acids; it can be dissolved easily in many organic solvents and has special chemical activity. So, it is an important raw material for the production of paper, coatings, inks, rubber, soaps, electronic industrial products, food grade ester gum, rosin ester resins etc.
Rosin is a kind of oil tree rosin in the pine family, the main component is C19H29COOH. Divided into "fat rosin", "wood rosin" and "floating rosin" 3 kinds. It should be used in industry, flux, paper making, string Musical Instruments, etc.
