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.

Storing and Transporting: Gum rosin must be kept away from heat and flame.

Package: Packed with 225/230kgs net each galvanized iron drum.
