Description

Rosin, Fumarated, Polymer With Diethylene Glycol is a specialized polymeric resin derived from modified rosin, offering enhanced thermal stability and compatibility. This product is valued for its ability to act as a tackifier and modifier, improving adhesion and film-forming properties in various formulations. It is primarily needed by manufacturers in the adhesives, coatings, printing inks, and polymer compounding industries seeking high-performance, bio-based resin components.

Application

• Hot-Melt Adhesives (HMAs): As a key tackifying resin to enhance bond strength, open time, and flexibility.
• Pressure-Sensitive Adhesives (PSAs): Used in tapes and labels to improve peel adhesion and tack.
• Industrial & Protective Coatings: Functions as a film-forming agent and modifier to increase hardness and chemical resistance.
• Printing Inks: Imparts gloss, rub resistance, and improved pigment wetting in solvent-based and publication gravure inks.
• Polymer Modification: Acts as a processing aid and compatibilizer in rubber and plastic compounds.
• Sealants and Caulks: Enhances cohesion, adhesion, and sag resistance.
