Gum Copal is a natural resin of plants of the Daniellia genus. Its application is important in the production of varnish, incense sticks, paint, paper coating, and many more.
--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.
Gum copal is a resin produced by the sap of forest tree in the genus Daniellia.
Due to common impurities and differences in regions, gum copal ranges in color from black to yellow to white. Gum copal, along with ivory and slaves, was a significant export from East Africa in the nineteenth century.
It can have an appearance similar to amber and may be mistaken for it. Unlike amber, gum copal is usually only 100-1,000 years old and it has not yet fossilized.

Damar is a non-timber forest product that has long been known, namely a sap which is a polysaccharide compound produced by certain types of forest trees.
damar batu is sap that has become fossilized. This sap is obtained from the soil. damar batu is resin undergoes a natural process hardening. In general, damar batu has a slightly increased color, there are also resin stones that are brown, white, even now. The texture of the mastic itself is much harder than copal and cat's eye resin. Stone resin is obtained from trees of the Dipterocarpaceae species.
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.
