Gum Copal

Gum copal is a natural resinous material of plant Agathis dammara (family Burseraceae). It has been used as a raw material for varnish because it produces glossy films with good weather protection properties. It has been used as pigment binder in varnishes due to the excellent binding properties. It has been mainly used as an emulsifier and stabilizer for the production of colour, paints, printing inks, aromatic emulsions and meat preservatives. Interestingly, Gum Copal was also used as medicine for several different ailments such as in the treatment of burns, headache, nosebleed, fever, stomach ache, and in the preparation of dental products and as remedy for loose teeth and dysentery.
