Description

Product Detail

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

Application

1. Foodstuff Industry - Gum Rosin is firstly converted into hydrogenated rosin, and then used to produce chewing gum

2. Paints & Coating Industry - Rosin is a basic material for paint industry because rosin is easy to dissolve in alcohol,
, turpentine and others organic solvent. Rosin always is converted to resinate, and then refine with drying oil such as tung oil and mix with volatility solvent to produce various lacquers. Rosin also take important role in producing road coating, rosin firstly converted to rosin malefic ester or polymerized rosin or disproportionated rosin Polyols ester, and then used to make thermoplastic coating for road sign inunction.

3. Metal Processing Industry - Rosin mainly is used as solding aid and metal polishing agent. Rosin is a kind of weak acidity matter, it can remove oxidation film from metal surface and slightly erode the surface of metal, and therefore, lots of solding aid agents contain rosin.

4. Construction Materials Industry - Rosin mainly is used as concrete frothing agent and floor tiling adhesive.

5. Papermaking Industry - Most rosin was applied to papermaking industry as sizing agent. Rosin paper sizing agent can prevent printing oil soaking and dispersing from paper, improves the strength and smoothness of paper; enhances the anti-abrasion of paper. But crystal rosin is unfit for making paper sizing agent due to difficulty of saponification, subsequently makes spot on the paper; sometimes even makes the pipe jam in paper sizing agent producing.

6. Printing Inks Industry - Rosin mainly act as color carrier and enhance color adhesive ability in printing ink. It takes about 7% of quality of printing oil in China. Rosin is converted into modified p henolic rosin with softening point of 160 to 175Celsius degrees and below 20 acid value when it is used in offset printing ink producing. In photogravure printing ink
producing, rosin firstly is converted into metal salt rosin with softening point of 125 to 135 Celsius degrees and below 95
acid value. For polymerized rosin, it can be used to producing various special printing ink.

7. Bactericide Industry - Rosin can be converted into abietylamine acetate for killing algae, bacteria, mildew, mollusk and
others pest.

8. Adhesives & Sealants Industry - Rosin was widely used as an ingredient of some kind of adhesive; especially in heat melt adhesive, pressure sensitive adhesive and rubber adhesive. Rosin mainly is used to enhance the strength, plasticity and viscosity of adhesive.

9. Electrical Equipment Industry - Rosin is used as insulation material in electric equipment industry; China has long history of applying rosin as insulation material in cable industry. Rosin also can mix with bakelite and others artificial resin to soak and besmear electric loop.

10. Fine chemicals Industry - Abietic acid is the main ingredient of rosin, it can be synthesized with others matter to produce series optics reactive materials and biotic reactive materials; these materials have special function for human and others organism.

11. Synthetic Rubber Industry - Rosin is used as softener in synthetic rubber industry; it enhances the plasticity, tear
strength, heat resistance, flexibility and anti-abrasion of synthetic rubber; also rosin can be use as dispersant and
emulsification in synthetic rubber industry. After seventies of twenty century, about 20% of total annual output of rosin was used synthetic rubber industry.
