Gum rosin also called colophony, is a solid form of resin obtained from pines and some other plants, mostly conifers, produced by heating fresh liquid resin to vaporize the volatile liquid terpene components. It is semi-transparent and varies in color from yellow to black. At room temperature rosin is brittle, but it melts at stove-top temperatures. It chiefly consists of different resin acids, especially abietic acid.


Application:
1) Can be dissolved easily in many organic solvents.
2) Has special chemical activity.
3) An important raw material for the production of paper, coatings, inks, rubber, soaps, electronic industrial products, food grade ester gum, and rosin ester resins.
