Gum Copal Gum Damar Copal Resin

Source: Gum Copal or Dammar Gum, is obtained from the Agathis Tree Dipterocarpaceae family of trees in Indonesia and East Asia. Most gum copal are produced by tapping trees; however, some is collected in fossilized form from the ground. The gum varies in colour from clear to pale yellow, while the fossilized form is grey-brown. Dammar gum is a triterpenoidresin, containing a large number of triterpenes and their oxidation products. Uses: Gum Copal or Damar Gum is used in foods, as a clouding or glazing agent, and in incense, varnish, and other products. Dammar varnish, made from Gum Copal mixed with turpentine, is commonly used in oil painting, both during the painting process and after the painting is finished.Gum Copal or Dammar Gum crystals are also dissolved in molten paraffin wax to make batik, to prevent the wax from cracking when it is drawn onto silk or rayon.The gum is stable, probably combustible, and incompatible with strong oxidizing agents. Its toxicity is low.Gum resins containing essential oils (ammoniacum, asafoetida, gamboge, myrrh, and scammony) are more largely used for therapeutic purposes and incense.Its properties of water resistance, solubility in alcohols, ability to give glossy finishing and superior binding abilities make it an important source of raw materials for the production of Varnishes, Adhesives, Paints and perfumes, Printing Inks, Aromatic Emulsions, Meat Preservative and Films.
