PM-004 Maleic Modified Glycerol Ester of Gum Rosin 130 PT Nasco - TBI

PT Nasco offers premium-quality Maleic Modified Glycerol Ester of Gum Rosin 130, a high-performance bio-based tackifying resin produced by the maleic modification and subsequent glycerol esterification of refined Gum Rosin derived from sustainably sourced Indonesian pine oleoresin. This advanced resin is engineered to provide enhanced thermal stability, improved adhesion, superior oxidation resistance, and excellent compatibility with a wide variety of elastomers and polymer systems. With its high softening point and outstanding tackifying efficiency, Maleic Modified Glycerol Ester of Gum Rosin 130 is widely used in premium hot melt adhesives, pressure-sensitive adhesives, road marking paints, printing inks, coatings, rubber compounding, and specialty industrial formulations requiring superior heat resistance and cohesive strength.
