Description

Rosin, Polymer With Formaldehyde, Glycerol, Octylphenol And Polymd. Rosin is a chemically modified rosin ester, specifically a polymerized phenolic-modified rosin ester. This specialized resin offers enhanced thermal stability, improved adhesion, and excellent compatibility with a wide range of polymers and solvents, making it a critical performance additive. It is primarily utilized in the formulation of high-performance adhesives, coatings, and inks where robust tackifying and film-forming properties are required. The CAS number for this compound is 70955-45-2.

Application

• Hot-Melt Adhesives (HMAs): Serves as a key tackifier and modifier, improving adhesion to various substrates including plastics, metals, and paper.
• Pressure-Sensitive Adhesives (PSAs): Enhances tack, peel strength, and shear resistance in tapes, labels, and graphic films.
• Industrial and Protective Coatings: Used as a resin modifier to improve gloss, hardness, and chemical resistance in solvent-based and high-solid coatings.
• Printing Inks: Acts as a resinous binder in gravure and flexographic inks, providing good pigment wetting and printability.
• Rubber Compounding: Functions as a processing aid and tackifier in rubber formulations for tires and industrial rubber goods.
• Sealants and Caulks: Imparts flexibility, adhesion, and durability in construction and automotive sealant applications.
