Applications of 8050-09-7
| Industry | Application | Process |
|---|---|---|
| Adhesives Industry | Tackifying resin for hot-melt adhesives, pressure-sensitive adhesives, and rubber-based adhesives | Blended with polymer matrices (e.g., EVA, SBS, natural rubber) in the molten state to impart tack and initial adhesion. |
| Paper Industry | Paper sizing agent | Converted into rosin size (e.g., maleic rosin size or dispersed rosin size) via saponification, then added to pulp; precipitated onto fiber surfaces in combination with alum (aluminum sulfate) to confer water resistance and ink resistance. |
| Coatings & Inks Industry | Alkyd resins, modified resins, ink vehicles | Processed into rosin esters via esterification with polyols (e.g., glycerol, pentaerythritol) or into maleic rosin via addition reaction with maleic anhydride, enhancing film hardness, gloss, and drying speed; used as carriers and pigment dispersants in inks. |
| Electronics Soldering Materials | Electronic flux | Rosinic acid and its salts serve as active ingredients to dissolve metal surface oxides, reduce solder surface tension, and promote wetting during soldering; commonly employed as base materials for no-clean fluxes. |
| Rubber Industry | Rubber plasticizer, tackifier, emulsifier | Incorporated during rubber compounding to enhance tack for improved shaping and processing performance; also functions as an emulsifier in the polymerization of synthetic rubbers (e.g., styrene-butadiene rubber). |
| Food Industry | Food additive (chewing gum base, emulsifier) | Refined and esterified (typically to glycerol esters) for use in chewing gum bases to modulate chew texture, or as a turbidity agent in beverages and as a protective edible coating for citrus fruits. |
| Pharmaceutical Industry | Pharmaceutical excipient, transdermal absorption enhancer | Used in refined form as a matrix component in rigid plasters (e.g., adhesive plasters), leveraging its tack and ability to facilitate drug permeation through the skin; certain modified derivatives exhibit antimicrobial activity. |
| Personal Care & Fine Chemicals | Raw material for soaps, toothpastes, and cosmetics | Rosin or its sodium salt enhances foam stability and cleaning efficacy in soap manufacturing; hydrogenated rosin and its derivatives serve as binders or film-forming agents in cosmetics. |
| Construction Materials | Concrete air-entraining agent, waterproofing agent | Sodium rosin salt is mixed with a binder solution to produce concrete air-entraining agents, introducing fine air voids to improve freeze-thaw resistance; its hydrophobic nature is also utilized in formulating construction waterproofing agents. |
