Suitable for paper making, coating, printing ink, rubber, soap, electronics, edible ester gum, rosin ester resin and other important industrial raw materials.
Features:
Rosin is obtained by cutting resin juice directly from the trunk of pine trees.A 13cm cut was made in the trunk of the grown pine tree to collect the colorless and fragrant viscous liquid that flowed from the tree. The liquid was distilled by steam vacuum. The distillate was turpentine, and the residue in the kettle was rosin.Rosin is characterized by light color, high acid value, high softening point, used for making washing soap, metal soap, varnish, ink, welding materials, insulating materials.

Gum rosin is a natural solid form distilled from oleo pine resin, which is derived from the â??Marcusiiâ?? Pine Trees in Indonesia.
It is yellowish, semi-transparent, insoluble in water but soluble in many organic solvents.
They are widely used, especially for basic materials for various industries ranging from the paper sizing, additives, printing inks, automotive industry, electronic devices, paints, cosmetics, varnishes, adhesives ( glues), sealing wax, batik, etc.

Gum Rosin is a natural organic compound derived from
Oleo Pine Resin. It is a yellowish solid vitreous product
which results from the distillation of Oleo Pine Resin. It is
known for its purity and high quality, and it is available in
WW and X grade to meet the varied requirement of different
industries.
CHEMICAL AND PHYSICAL CHARACTERISTICS:
H.S. CODE:3806.10.00, CAS number: 8005-09-07
USES of GUM ROSIN:
Paints Paper, Polish, Phenyl, Soap, Cracker, Rubber, Ink, soldering fluxes,
Intermediate material for synthetic organic chemicals
--Application--
1. Foodstuff Industry - Gum Rosin is firstly converted into hydrogenated rosin, and then used to produce chewing gum
2. Paints & Coating Industry - Rosin is a basic material for paint industry because rosin is easy to dissolve in alcohol,turpentine and others organic solvent. Rosin always is converted to resinate, and then refine with drying oil such as tung oil and mix with volatility solvent to produce various lacquers. Rosin also take important role in producing road coating, rosin firstly converted to rosin malefic ester or polymerized rosin or disproportionated rosin Polyols ester, and then used to make thermoplastic coating for road sign inunction.
3. Metal Processing Industry - Rosin mainly is used as solding aid and metal polishing agent. Rosin is a kind of weak acidity matter, it can remove oxidation film from metal surface and slightly erode the surface of metal, and therefore, lots of solding aid agents contain rosin.
4. Construction Materials Industry - Rosin mainly is used as concrete frothing agent and floor tiling adhesive.
5. Papermaking Industry - Most rosin was applied to papermaking industry as sizing agent. Rosin paper sizing agent can prevent printing oil soaking and dispersing from paper, improves the strength and smoothness of paper; enhances the anti-abrasion of paper. But crystal rosin is unfit for making paper sizing agent due to difficulty of saponification, subsequently makes spot on the paper; sometimes even makes the pipe jam in paper sizing agent producing.
