Usage: 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.
