Light yellow-amber rosin flakes from Pinus Elliottii for versatile uses.
Gum Rosin Flakes, Brazilian, WW Grade
Gum Rosin Flakes, also known as colophony, are light yellow-amber in color and sourced from Pinus Elliottii, commonly known as the slash pine. This WW grade rosin complies with Class A, Type I, Grade WW Mil. Spec. A-A-59142. It is supplied in a mixture of small and large flakes, crystals, occasional large lumps, and fine powder. The product is brittle at room temperature but melts at stove-top temperatures. Gum Rosin Flakes are widely used in printing inks, varnishes, adhesives, soaps, sealing wax, soldering fluxes, depilatory hard wax, and paper sizing. 550 lb pallets of rosin are available at discounted prices or free shipping within parts of the U.S.

- Brazilian rosin is a good choice for scalding hogs—provided its properties (a slightly higher softening point and lower tackiness) result in a more controlled adhesion that minimizes skin damage and eases cleanup.
Caution:
Store in a cool, dry place. Handle with proper safety precautions. Refer to the SDS for detailed safety and handling instructions.
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.
