Usage:
At present,most rosin product is used for the manufacturing of paper,paint,adhesive,rubber,soap and printing ink..Since rosin is easily softened and oxidized,in the oil paint industry,the carboxylation reaction of resin acid is employed to produced 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.

In galvanized iron drum of 225KGS net each,each 20' container can be loaded 80 drums with pallet.96 drums without pallet.
