Description

Fatty Acids, Cottonseed-Oil, Polymers With p-tert-Butylbenzoic Acid, Pentaerythritol And Phthalic Anhydride CAS NO 69012-05-1 is a specialized synthetic resin derived from modified vegetable oil fatty acids and aromatic components. This compound is engineered to provide a unique balance of flexibility, adhesion, and chemical resistance, making it a critical performance additive in advanced coating and adhesive formulations. It is primarily utilized by manufacturers in the paints & coatings, printing inks, and industrial adhesive sectors seeking to enhance product durability and application properties.

Application

• Alkyd Resin Modifier: Used to improve flexibility, drying time, and gloss retention in solvent-based and high-solid alkyd coatings.
• Industrial & Protective Coatings: Serves as a key resin component in primers, enamels, and maintenance paints for metal, wood, and concrete substrates.
• Printing Inks: Imparts excellent pigment wetting, flow, and adhesion in gravure, flexographic, and specialty ink systems.
• Adhesive Formulations: Enhances tack, peel strength, and thermal stability in pressure-sensitive and structural adhesives.
• Plasticizer & Stabilizer: Acts as a secondary plasticizer and stabilizer in polymer compositions, including PVC and rubber compounds.
• Corrosion Inhibitive Primers: Formulated into primers where its film-forming properties contribute to barrier protection against corrosion.
