Description

Fatty Acids, C16-18 And C18-Unsatd., Polymers With p-tert-Butylbenzoic Acid, Peanut-Oil Fatty Acids, Pentaerythritol And Phthalic Anhydride is a specialized polymeric resin derived from a complex formulation of fatty acids and polyols. This product is engineered to deliver enhanced flexibility, adhesion, and chemical resistance in demanding coating and adhesive formulations. It is primarily utilized by manufacturers in the paints & coatings, printing inks, and industrial adhesive sectors seeking to improve product performance and durability.

Application

• Alkyd Resin Modifier: Used to impart flexibility and improve weathering resistance in air-drying and baking alkyd coatings.
• Industrial & Protective Coatings: A key component in primers, topcoats, and marine paints where durability and adhesion to metal substrates are critical.
• Printing Inks: Enhances gloss, flow, and pigment wetting in offset and gravure printing ink formulations.
• Adhesives & Sealants: Functions as a tackifier and flexibilizer in solvent-based and hot-melt adhesive systems.
• Plasticizer & Compatibilizer: Improves the compatibility and processing of polymer blends.
• Wood Finishes: Used in varnishes and stains to enhance penetration and film formation.
