PM-002 Gum Rosin PT Nasco - TBI

PT Nasco offers premium-quality Gum Rosin, a natural resin obtained from the distillation of oleo pine resin collected from sustainably managed Sumatran Pine (Pinus merkusii) forests. During the distillation process, the volatile Gum Turpentine Oil is removed, leaving behind high-purity Gum Rosin composed primarily of naturally occurring resin acids. Carefully processed to deliver consistent quality, Gum Rosin is widely used as a renewable, bio-based raw material for adhesives, inks, paints, coatings, rubber compounding, paper sizing, road marking paints, and numerous specialty chemical applications. Its excellent tackifying properties, strong adhesion, and compatibility with a wide range of polymers make it an essential ingredient across many industrial formulations. PT Nasco operates a vertically integrated production process from sustainably managed pine forests in Sumatra through its Indopine product line. (indopine.com)
