Description

Fatty Acids, Tall-Oil, Polymers With Bisphenol A, Formaldehyde, Glycerol, Phthalic Anhydride And Rosin is a complex, high-performance polymeric resin derived from renewable tall oil fatty acids and rosin, modified with key synthetic components. This specialized chemical offers a unique balance of tack, adhesion, and thermal stability, making it a critical formulation component for advanced industrial materials. It is primarily required by manufacturers in the adhesives, coatings, and ink industries seeking to enhance product performance with bio-based content.

Application

• Hot-Melt Adhesives (HMA): Acts as a key tackifying resin to improve initial grab, peel strength, and flexibility in packaging, woodworking, and non-woven adhesives.
• Pressure-Sensitive Adhesives (PSA): Used in the formulation of tapes, labels, and graphic films to provide balanced adhesion and cohesion properties.
• Industrial and Protective Coatings: Imparts excellent adhesion to metallic and difficult substrates, along with corrosion resistance and gloss in solvent-based coatings.
• Printing Inks: Serves as a resinous vehicle in gravure and flexographic inks, contributing to pigment wetting, gloss, and printability on various films and foils.
• Rubber Compounding: Functions as a processing aid and tackifier in rubber products, improving compound homogeneity and green strength.
• Sealants and Caulks: Enhances adhesion, elasticity, and durability in construction and automotive sealant formulations.
