Description

Fatty Acids, Tall-Oil, Polymers With p-tert-Butylphenol, Formaldehyde, Maleic Anhydride, Pentaerythritol, Phthalic Anhydride And Rosin CAS NO 121053-15-4 is a complex, high-performance polymeric resin derived from renewable tall oil fatty acids and rosin, modified with key monomers to create a versatile chemical intermediate. This product matters because it offers a unique combination of properties including adhesion promotion, tack, and chemical resistance, making it a critical component for formulating high-performance industrial materials. It is primarily needed by manufacturers in the adhesives, coatings, printing inks, and rubber compounding industries seeking to enhance product durability and performance.

Application

• Hot-Melt Adhesives (HMA): As a key tackifier and modifier to improve adhesion, cohesion, and thermal stability.
• Pressure-Sensitive Adhesives (PSA): To enhance peel strength, tack, and shear resistance in tapes and labels.
• Industrial and Protective Coatings: As a resin modifier to improve film hardness, gloss, and chemical resistance.
• Printing Inks: Used in gravure and flexographic inks to promote pigment wetting, gloss, and substrate adhesion.
• Rubber Compounding: Acts as a processing aid and tackifier in rubber products like tires and industrial belts.
• Sealants and Caulks: To impart flexibility, adhesion, and durability in construction and automotive sealants.
• Foundry Resins: As a binder component in sand cores and molds for metal casting.
