1.General Information: CAS No.: 8050-09-7 Einecs: 232-475-7 Formula: C19H29COOH Molecular weight: 302.451 Hs code:3806101000 2.Specification: | Specification | Standard | | Appearance | Light Yellow Crystal | | Color (Gardner) | 8.0 Max | | Softening Point | 76.0 Min | | Acid Value (mgKOH/g) | 166.0 Min | | Ash content (PCT) | 0.020 Max | | Non saponification content (PCT) | 5 Max | | Undissolvable object in alcohol (PCT) | 0.030 Max | 3.Usage: In the soap insdustry: When cooked with soda ash or caustic soda, Gum rosin can form a rosin soap. Rosin soap has great soap detergency, easily soluble in water, it can dissolve the fat, easy to lather. Rosin is sticky, it can make soap not easily crack and rancidity deterioration. In the paint and coating industry: Gum Rosin is easily soluble in various organic solvents, and easy to film. It is shiny, is one of the basic raw material for paint. The role of rosin in paint is to brighten paint color, fasten drying, and make the film smooth and not easy to fall off. 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. 4.Package: 225kg/drum, 18MT/20'FCL. |
