Gum Rosin

Gum Rosin is a natural solid resin obtained from living pine trees. It is composed primarily of abiotic-type resin acids. This versatile material appears as translucent, brittle solid pieces with a color ranging from yellow to dark amber. It is insoluble in water but soluble in many organic solvents. Gum Rosin is valued for its tackifying, emulsifying, and film-forming properties, serving as a crucial renewable raw material in numerous industries.

The main detailed uses of the product
  • Adhesives & Sealants
    Adhesives & Sealants

    Primarily used as a key tackifier in pressure-sensitive adhesives (e.g., tapes, labels) and hot-melt adhesives. It enhances initial tack, adhesion, and bond strength to various substrates.

  • Printing Inks
    Printing Inks

    Acts as a primary resin binder in gravure and flexographic inks. It provides excellent pigment wetting, gloss, and rapid setting properties on paper and film substrates.

  • Rubber Compounding
    Rubber Compounding

    Used as a natural processing aid and tackifier in rubber products like tires and conveyor belts. It improves plasticity during mixing and enhances the tackiness of uncured rubber compounds.

  • Soldering Flux
    Soldering Flux

    Serves as the core active ingredient in rosin-based soldering fluxes. Its mild acidity cleans metal surfaces, promoting solder wetting and forming strong, reliable electrical connections.
