Rosin (also known as colophony) is a solid resinous material obtained from the oleoresin (tree sap) of live pine trees (called gum rosin), the stump wood of dead pine trees by solvent extraction (called wood rosin), and in the pulp paper recovery process (called tall oil rosin).
USAGE: The rosin is used directly in the manufacturing of adhesives, inks, rubber compounds, paints & coatings, etc., or modified as resins to give more specific characteristics to the rosin to improve or change their stability, aging, color, tackiness, and so forth to be used in the above-mentioned products.
