Features:
1) China original gum rosin WW grade
2) Natural organic compound, mainly composed of resins
3) Possesses chemical activity when dissolved in many organic solvents
4) Used for the manufacturing of paper, paint, soap and printing ink
5) Easily softened and oxidized
6) In the oil paint industry, the carboxylation reaction of resin acid is usually employed to produce resinate for further use
7) In the producing of synthetic rubber and printing ink, resin acid is changed into disproportionate rosin, polymerized rosin, hydrogenated rosin, for further use by its double bond reaction
