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. | | Packing, Storing and Transporting of Gum Rosin: In galvanized iron drums of about 225/230kgs net each, must be kept away from heat and flame. | |
