Description

Castor Oil, Dehydrated, Polymer With Glycerol, Phthalicanhydride, Soybean Oil, Styrene And Vinyltoluene CAS NO 68443-27-6 is a specialized alkyd resin modifier derived from a complex polymerization of dehydrated castor oil, soybean oil, and aromatic monomers. This product matters as a high-performance additive that imparts exceptional flexibility, adhesion, and chemical resistance to coatings, inks, and adhesives. Industrial formulators and manufacturers in the protective coatings, graphic arts, and specialty polymer sectors need this resin to enhance the durability and functional properties of their end products.

Application

• As a flexibilizing and adhesion-promoting agent in high-performance industrial and marine coatings.
• Key modifier in air-drying and baking enamels for improved film formation and gloss retention.
• Component in specialty printing inks, including overprint varnishes and metal-decorating inks, for enhanced rub resistance and substrate adhesion.
• Used in the formulation of corrosion-resistant primers and maintenance paints.
• As a reactive diluent and backbone modifier in synthetic resin and adhesive systems.
• Imparts improved water and alkali resistance in architectural and appliance coatings.

Quality Control

Our alkyd resin modifiers are manufactured under a strict quality management system to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, viscosity, solids content, and color are rigorously tested. A Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to guarantee compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from strong acids and organic solvents. Under these conditions, the product has a typical shelf life of 24 months from the date of manufacture.
