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. | |

Features:
1) China original gum rosin
2) Natural organic compound, mainly composed of resins
3) Possesses chemical activity when dissolved in many organic solvents
4) Used for the manufacturing of paper, paint, soap and printing ink
5) Easily softened and oxidized
6) In the oil paint industry, the carboxylation reaction of resin acid is usually employed to produce resinate for further use
7) In the producing of synthetic rubber and printing ink, resin acid is changed into disproportionate rosin, polymerized rosin, hydrogenated rosin, for further use by its double bond reaction
Usage: It is used in paper, ink, rubber, paints and varnish, various adhesives, glue, soap, synthetic resins, chewing gum and other chemical industries.
