Gum Rosin/Colophony/Pine rosin

Appearance:transparent solid

Introduction:
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.

Uses of Gum Rosin: At present, most rosin product is used for the 
manufacturing of paper, paint, soap and printing ink. Since rosin is 
easily softened and oxidized, in the oil paint industry, the carboxylation 
reaction of resin acid is usually employed to produce resonates for 
further use.While in the producing of synthetic rubber and printing ink, 
resin acid is changed into disproportionate rosin, polymerized rosin, 
hydrogenated rosin, etc for further use by its double bond reaction.
