Description

Rosin, Polymer With Phenol CAS NO 68083-03-4 is a high-performance phenolic-modified rosin resin, engineered to enhance adhesion, tack, and thermal stability in demanding formulations. This specialized polymer is critical for industries requiring robust binding agents with excellent compatibility in solvent-based and hot-melt systems. It is an essential raw material for manufacturers in the adhesives, coatings, printing inks, and rubber compounding sectors seeking to improve product performance and durability.

Application

• Pressure-Sensitive Adhesives (PSAs): A key tackifier and modifier in tapes, labels, and films.
• Hot Melt Adhesives: Enhances open time, specific adhesion, and thermal stability for packaging, woodworking, and non-wovens.
• Industrial & Protective Coatings: Improves gloss, hardness, and chemical resistance in varnishes and metal primers.
• Printing Inks: Used as a resin vehicle to promote pigment wetting, gloss, and rub resistance.
• Rubber Compounding: Acts as a processing aid and tackifier in tire and mechanical goods manufacturing.
• Sealants and Caulks: Provides improved adhesion and flexibility.
• Foundry Resins: Serves as a core binder component in shell molding processes.
