Description

Soyabean Oil/Rosin/Isophthalic Acid/Glycerol Alkyd Resin is a specialized, modified alkyd resin engineered for high-performance industrial coatings. This product offers a unique balance of properties derived from its hybrid composition, including excellent adhesion, flexibility, and chemical resistance. It is a critical raw material for formulators in the protective coatings, marine paints, industrial maintenance finishes, and printing inks sectors seeking durable and cost-effective binder solutions.

Application

• Protective & Marine Coatings: As a primary binder in anti-corrosive primers and topcoats for steel structures, ships, and offshore platforms.
• Industrial Maintenance Paints: Used in finishes for factory equipment, storage tanks, and machinery requiring durability.
• Printing Inks: Serves as a resin vehicle for high-gloss, quick-setting inks, particularly for packaging and publications.
• Architectural Enamels: Formulated into high-quality, gloss and semi-gloss enamels for interior and exterior architectural applications.
• Automotive Refinish Paints: Employed in repair primers and finishes that demand good sanding properties and adhesion.
• Wood Finishes: Used in varnishes and stains to provide a tough, protective film with good clarity and yellowing resistance.
• Metal Decorating Coatings: Applied in coatings for food and beverage cans, drums, and other metal packaging.

Quality Control

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

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flames. The product is susceptible to oxidation; keep containers tightly sealed when not in use. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F).
