Gum Rosin Lumps, Honduran, Grade WG/WW

Honduran Gum Rosin Lumps (HROSIN) are high-grade colophony derived from the Pinus Oocarpa species in Honduras. This semi-transparent pine rosin varies in color from pale yellow to light brown and contains about 10% natural unsaponifiable matter, which imparts excellent anticrystalline properties to the rosin and its compounds. The product is widely used in adhesives, coatings, chewing gums, cosmetics, linoleum, paints, printing inks, resins, rubber, sizes, and varnishes.
