Alcohol-Soluble White Rosin AS18 Pale hue As an additive it enhances the adhesion between the paint film and the road surface
Alcohol-soluble white rosin is a high-quality rosin produced from premium resinous rosin through specific refining processes (such as distillation, decolorization, and filtration). This product features a light color, stable acid value, and undergoes special treatment to minimize insolubles and impurities. Its most distinctive characteristic is excellent solubility in alcohol solvents like ethanol and isopropanol, yielding clear, transparent solutions. It serves as an ideal natural resin raw mat

I. Product Overview:
Alcohol-soluble white rosin is a high-quality rosin produced from premium resinous rosin through specific refining processes (such as distillation, decolorization, and filtration). This product features a light color, stable acid value, and undergoes special treatment to minimize insolubles and impurities. Its most distinctive characteristic is excellent solubility in alcohol solvents like ethanol and isopropanol, yielding clear, transparent solutions. It serves as an ideal natural resin raw material for formulating high-performance alcohol-soluble coatings, inks, adhesives, and various additives.

III. Product Characteristics:
Excellent Alcohol Solubility: Rapid dissolution in solvents such as ethanol and isopropanol, yielding highly transparent solutions free of suspended particles or sediment, facilitating production and formulation adjustments.
Light Color: Refined processing results in a lighter hue than standard rosin, suitable for light-colored or white products with stringent color requirements.
Superior Adhesion and Film-Forming Properties: Significantly enhances coating or adhesive film adhesion to diverse substrates (e.g., metal, glass, plastic, paper), forming a glossy, hard, and brittle paint film.
Excellent Compatibility: Compatible with nitrocellulose, shellac, plasticizers, and various synthetic resins. Can be blended to optimize product performance.
Natural Renewable Resource: Derived from sustainably managed pine forests, it serves as an eco-friendly natural chemical raw material.
IV. Product Applications:
Coatings Industry:
Alcohol-Soluble Self-Drying/Baking Varnishes: Functions as primary film-forming or tackifying resin for decorative and protective coatings on metals and wood.
Metal Foil Coatings: Provides protective layers for gold foil, copper foil, etc., delivering gloss and oxidation resistance.
Road marking paint: As an additive to enhance adhesion between the paint film and road surface.
Printing Ink Industry:
Flexographic printing inks: One of the key binders in alcohol-soluble flexographic inks, providing excellent adhesion to substrates (e.g., films, paper), fast drying, and gloss.
Gravure printing inks: Used in alcohol-soluble gravure ink systems.
Composite Inks: Serves as a binder component in plastic film composite packaging inks.
Adhesive Industry:
Pressure-Sensitive Adhesives: Functions as a tackifying resin in alcohol-soluble pressure-sensitive adhesive formulations for labels, tapes, etc.
Hot-Melt Adhesives: Can serve as a tackifying resin component, though thermal stability must be considered.
Encapsulation Adhesives: Used in alcohol-soluble encapsulation adhesives with specific requirements.
Other Applications:
Varnishes: Used for coating paper or paper products to enhance surface gloss and abrasion resistance.
Fluxes: Serves as a film-forming agent in alcohol-soluble flux formulations.
V. Product Packaging:
25 kg per bag. Store in a cool, dry, well-ventilated warehouse, away from direct sunlight and high temperatures. Keep away from ignition sources and heat.
