Application

GUM ROSIN serves multiple purposes across various industries due to its natural resin properties derived from pine tree oil and wood pulp processing residues. With a slight turpentine odor, it can be utilized as a glazing agent in medicines and chewing gum, enhancing their qualities. In industrial applications, GUM ROSIN functions as an essential flux in soldering processes. It is also integral in creating polishing surfaces for optics manufacturing, where it is combined with pitch to finely polish glass lenses. Additionally, GUM ROSIN finds use as a flotation agent, sizing compound, and in the production of lacquers and plasticizers. It is valuable for providing grip to violinists' bows-termed colophony-and aids in the traction for dancers' and boxers' shoes. Color variations in GUM ROSIN range from colorless to black, demonstrating its versatility and broad application scope.
