Description

Rosin, Polymer With Dicyclopentadiene, Formaldehyde And Nonylphenol CAS NO 68458-68-4 is a high-performance, modified rosin resin engineered for demanding industrial applications. This specialized polymer offers enhanced thermal stability, improved adhesion, and excellent compatibility with a wide range of polymers and solvents. It is a critical raw material for formulators in the adhesives, coatings, and ink industries seeking to improve product performance and durability.

Application

• Hot Melt Adhesives (HMA): As a key tackifier providing excellent initial grab, peel strength, and thermal stability.
• Pressure-Sensitive Adhesives (PSA): Used in tapes and labels to enhance tack, adhesion, and cohesive strength.
• Industrial and Protective Coatings: Imparts improved hardness, gloss, and water resistance to alkyd and epoxy-based coatings.
• Printing Inks: Acts as a resin binder for gravure and flexographic inks, improving pigment wetting and print quality.
• Rubber Compounding: Functions as a processing aid and tackifier in rubber products.
• Sealants and Caulks: Enhances adhesion and flexibility in construction and automotive sealants.
