High quality with ww grade Rosin Gum

Rosin (also known as colophony) is a solid resinous material obtained from the oleoresin (tree sap) of live pine trees (called gum rosin), the stump wood of dead pine trees by solvent extraction (called wood rosin), and in the pulp paper recovery process (called tall oil rosin).

1) Special properties: natural organic compound, mainly composed of resins,

   possesses chemical activity when dissolved in many organic solvents

2) Applications: used for manufacturing of paper, paint, soap and printing ink

   a) 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

   b) 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

USAGE: The rosin is used directly in the manufacturing of adhesives, inks, rubber compounds, paints & coatings, etc., or modified as resins to give more specific characteristics to the rosin to improve or change their stability, aging, color, tackiness, and so forth to be used in the above-mentioned products. 

Packing: Galvanized iron drum, 225kg net each drum.
