Product Description
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 rosin temperature 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.Multipurpose of rosin: In the production of glues, paints, vamishes, printing inks, sizing agents forpaper, rubber, adhesives, non - slipcoatings, leather, depilatory waxes.
Rosin Colophony is divided into six grades: special, first, second, third, fourth and fifth
The quality of rosin is determined by color, acid value, softening point, transparency, etc. Generally, the lighter the color, the better the quality; the more rosin acid content, the greater the acid value, and the higher the softening point.
