Rosin, also called colophony or Greek pitch, is a solid form of resin obtained from pines and some other plants, mostly from conifers. It is 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.
Chinese Gum 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 resinate 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.

Gum Rosin, also known as colophony or Greek pitch, is a solid resin derived from pine trees and some other plants, primarily conifers. It is produced by heating fresh liquid resin, which causes the volatile terpene components to evaporate. The result is a semi-transparent solid that ranges in color from yellow to black. Rosin is brittle at room temperature but melts at relatively low temperatures, such as those achieved on a stove. Its primary chemical components are resin acids, especially abietic acid.
Gum Rosin which preparated from China is commonly used in industries such as paper production, paint, soap, and printing ink. Since rosin tends to soften and oxidize easily, the oil paint industry often uses carboxylation of resin acids to produce resinates for further use. In the production of synthetic rubber and printing inks, resin acids undergo processes such as disproportionation, polymerization, or hydrogenation to form disproportionated rosin, polymerized rosin, or hydrogenated rosin, respectively. These reactions typically involve altering the double bonds in the resin acids to achieve the desired properties.
