Chinese Gum Rosin based products are 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.
Raw material for making soap, paper, oil paint, rubber and synthetic resins.
Gum Rosin is also used as an Intermediate for synthetic organic chemicals.
