Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Dicyclopentadiene, Fumaric Acid, Maleic Anhydride, Rosin And Soybean Oil is a complex, high-performance resinous polymer derived from renewable and petrochemical feedstocks, engineered for demanding industrial applications. This specialized compound offers a unique combination of tack, adhesion, and water resistance, making it a critical raw material for advanced formulation. It is primarily utilized by manufacturers in the adhesives, coatings, and ink industries seeking to enhance product durability and performance.

Application

• Hot-Melt Adhesives (HMA): A key tackifier and modifier, improving adhesion strength, thermal stability, and open time for packaging, woodworking, and non-woven applications.
• Pressure-Sensitive Adhesives (PSA): Functions as a core tackifying resin for labels, tapes, and graphic films, providing balanced peel and shear properties.
• Industrial & Protective Coatings: Imparts excellent water resistance, adhesion to difficult substrates, and film flexibility in corrosion-resistant and maintenance coatings.
• Printing Inks: Used as a resinous vehicle in gravure and flexographic inks, enhancing pigment wetting, gloss, and substrate adhesion.
• Rubber Compounding: Acts as a processing aid and reinforcing agent, improving dispersion of fillers and enhancing the physical properties of rubber products.
• Sealants and Caulks: Contributes to long-term elasticity, adhesion, and moisture barrier properties in construction and automotive sealants.
