Description

Soybean-Safflower Oil/Isophthalic Acid/Pentaerythritol CAS NO 68122-62-3 is a specialized alkyd resin intermediate, a co-polymer derived from the polycondensation of modified vegetable oils with isophthalic acid and pentaerythritol. This compound is engineered to provide superior performance characteristics, including enhanced durability, chemical resistance, and excellent film-forming properties, which are critical for high-performance coating formulations. It is primarily utilized by manufacturers in the paints, coatings, and industrial resins sectors seeking to develop premium products with improved weatherability and mechanical strength.

Application

• High-Performance Industrial Coatings: A key resin component for manufacturing durable coatings for machinery, agricultural equipment, and metal structures.
• Architectural Paints: Used in formulating exterior house paints and trim enamels that require excellent gloss retention and resistance to yellowing.
• Marine & Protective Coatings: Serves as a binder in anti-corrosive primers and topcoats for ships, offshore platforms, and coastal infrastructure.
• Automotive Refinish & OEM Coatings: Incorporated into coating systems that demand high chemical resistance, scratch resistance, and a superior finish.
• Wood Finishes & Varnishes: Used in high-quality clear coats and pigmented finishes for furniture and flooring due to its good flow and leveling.
• Printing Inks: Acts as a resinous vehicle for specialty inks requiring fast drying and good adhesion to various substrates.
• Adhesives & Sealants: Functions as a tackifying or modifying resin in formulations requiring strong bonding and flexibility.

Quality Control

Our Soybean-Safflower Oil/Isophthalic Acid/Pentaerythritol is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including measurement of acid value, viscosity, color, and solids content, aligning with industry specifications for alkyd resins. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory compliance needs.

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 material is light-sensitive and easily oxidized; prolonged exposure to air, heat, or light should be avoided to maintain product integrity and shelf life.
