Description

Soybean Oil, Phthalic Anhydride, Glycerol, Pentaerythritol Resin CAS NO 68458-10-6 is a specialized alkyd resin derived from the polycondensation of pentaerythritol with phthalic anhydride, modified with soybean oil and glycerol. This formulation is engineered to provide an excellent balance of flexibility, adhesion, and durability, making it a critical component in high-performance coating systems. It is primarily sought after by manufacturers in the paints, coatings, and industrial finishes sectors who require resins that offer superior film formation and weathering resistance.

Application

• Industrial and Architectural Paints: Used as a primary binder in air-drying and baking enamels for machinery, agricultural equipment, and structural steel.
• Protective Coatings: Formulated into corrosion-resistant primers and topcoats for metal substrates exposed to harsh environments.
• Printing Inks: Serves as a vehicle resin in specialty printing inks, contributing to gloss and rub resistance.
• Wood Finishes: A key component in varnishes and clear coatings for furniture and flooring, enhancing depth and protection.
• Adhesives and Sealants: Imparts tack and cohesive strength in certain industrial adhesive formulations.
• Marine Coatings: Utilized in coatings for boats and offshore structures due to its good water resistance.

Quality Control

Our alkyd resins are manufactured under a stringent quality management system. Each batch is tested against key parameters including acid value, viscosity, color, and solids content to ensure consistent performance and batch-to-batch uniformity. Certificates of Analysis (COA) documenting these specifications are available upon request.

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). This product is easily oxidized (store under inert atmosphere) and light-sensitive; prolonged exposure to air, heat, or direct light should be avoided to prevent skinning and gelation. Keep away from strong oxidizing agents.
