PM-003 Glycerol Ester of Gum Rosin 85 PT Nasco - TBI

PT Nasco offers premium-quality Glycerol Ester of Gum Rosin 85, a pale thermoplastic resin produced by the esterification of refined Gum Rosin with glycerol. Carefully manufactured from sustainably sourced Indonesian pine resin, this bio-based tackifying resin delivers excellent adhesion, compatibility with a wide range of polymers, and outstanding thermal stability for industrial formulations. Designed for demanding adhesive and coating applications, Glycerol Ester of Gum Rosin 85 exhibits excellent solubility in various polymer systems including EVA, SBS, SIS, SBR, natural rubber, and acrylic resins. Its light color, low odor, and superior tackifying performance make it an ideal ingredient for hot melt adhesives, pressure-sensitive adhesives, road marking paints, coatings, and specialty industrial products.
