what is gum rosin?

 

Rosin, also called colophony or Greek pitch (Latin: pix græca), 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 temperature. It chiefly consists of various resin acids, especially abietic acid. The term "colophony" comes from colophonia
resina, Latin for "resin from Colophon," an ancient Ionic city.

Gum Rosin Uses

 

Most rosin is used in a chemically modified form rather than in the raw state in which it is obtained. It consists primarily of a mixture of abietic-type and pimaric-type acids with smaller amounts of neutral compounds. This intrinsic acidity, coupled with other chemical properties, enables it to be converted to a Large number of downstream derivatives which are used in a wide range of applications. The derivatives include salts, esters and maleic,anhydride adducts, and hydrogenated, disproportionated and polymerized rosins. Their most important uses are in the manufacture of adhesives, paper sizing agents, printing inks, solders and fluxes, various surface coatings, insulating materials for the electronics industry, synthetic rubber, chewing gums and soaps and detergents. Rosin and its chemical derivatives are used chiefly to make soaps, varnishes, sealing wax, printing inks, driers, sizes for paper, adhesives, binders, soldering fluxes, gloss oils for paints, and pitch for casks. Rosin is also used on bows of violins and other stringed instruments, on the shoes of dancers, and on floors of studios and stages to prevent slipping.

Gum Rosin Raw Material

It is used in printing ink as color carrier, as welding flux and for polishing in metal processing, as an additive in soap, food, antiseptics and germicides

In Adhesive Industry:

Rubber based adhesive, synthetic resin based adhesive and vegetable adhesive all have rosin as one of their ingredients.

In the paint industry:
Rosin as a natural resin with abundant sources, is easily dried and smooth on its surface. It will continuously be the basic raw material for paint producing.

In printing ink industry:
rosin is mainly used as color carrier of the ink and to increase its adhesion to paper. Without rosin in the ink, the presswork will be blurred.

In the Papermaking Industry:
Sizing agent made from rosin can prevent ink from dispersion, improve the strength and smoothness and enhance abrasion resistant of the paper.

In the rubber industry:
rosin is used as a softening agent to make the rubber soft and easy for kneading, make the filling agent easily dispersed.
