Description

Fatty Acids, Tall-Oil, Polymers With Glycerol, Linseed Oil, Pentaerythritol And Phthalic Anhydride CAS NO 67700-57-6 is a complex, high-performance alkyd resin intermediate derived from renewable and synthetic raw materials. This specialized polymer is engineered to provide exceptional film-forming properties, durability, and chemical resistance in demanding industrial applications. It is a critical raw material for formulators in the coatings, inks, and adhesives industries seeking to enhance product performance with tailored resin solutions.

Application

• High-Performance Industrial Coatings: As a key binder in air-drying and baking enamels for machinery, agricultural equipment, and metal substrates requiring excellent gloss and weather resistance.
• Protective & Marine Coatings: Formulation of corrosion-resistant primers and topcoats for structural steel, ship hulls, and offshore installations.
• Printing Inks: Used in the manufacture of quick-setting, glossy overprint varnishes and specialty inks that demand good adhesion and rub resistance.
• Adhesives & Sealants: Serves as a tackifying and reinforcing agent in solvent-based adhesives, providing strong bonds and flexibility.
• Architectural Coatings: Modification of alkyd-based paints and varnishes for interior and exterior wood and trim to improve drying time and film hardness.
• Automotive Refinish: Component in repair paints and clear coats where fast dry time and high gloss are essential.

Quality Control

Our production of this alkyd resin intermediate adheres to strict batch-to-batch consistency protocols. Quality is monitored through key parameters including acid value, viscosity, solids content, and color. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to ensure the material meets your formulation requirements. We operate under a robust Quality Management System to guarantee reliability for industrial-scale buyers.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). Keep away from heat, sparks, and open flame. Due to its composition, the material should be stored under an inert atmosphere if long-term storage is anticipated to prevent skinning and oxidative cross-linking. Keep container tightly sealed when not in use to prevent solvent loss and skin formation.
