Gum Rosin
Synonyms: Colophony, Rosin
Gum rosin also called colophony, is a solid form of resin obtained from pines and some other plants, mostly conifers, produced by heating fresh liquid resin to vaporize the volatile liquid terpene components. It is semi-transparent and varies in color from yellow to black. At room temperature rosin is brittle, but it melts at stove-top temperatures. It chiefly consists of different resin acids, especially abietic acid.
Application:
Chemical material for Paper Production, Soap, Ink, Paints, Adhesives, Ruber, Synthetic Resin, Electric Insulation material, and Organic Synthesis
Packing: 25 kgs in kraft paper bags or 225 kgs in drums, 20/18MT/20'container
