Description

Sunflower Oil/ Phthalic Anhydride/ Glycerol Resin is a specialized alkyd resin derived from the polycondensation of phthalic anhydride, glycerol, and modified with sunflower oil fatty acids. This compound matters for its excellent film-forming properties, flexibility, and adhesion, making it a crucial component in high-performance surface coatings. Industrial manufacturers in the paints, varnishes, and protective coatings sectors need this resin to formulate durable, weather-resistant finishes for metal, wood, and other substrates.

Application

• Primary binder in air-drying and baking alkyd enamels for industrial and decorative applications.
• Formulation of corrosion-resistant primers and topcoats for metal structures, machinery, and automotive parts.
• Manufacture of wood finishes and varnishes, providing enhanced gloss, durability, and water resistance.
• Key component in maintenance and marine paints requiring robust protection against harsh environmental conditions.
• Used in specialty printing inks where good pigment wetting and film integrity are essential.
• Base for industrial maintenance coatings applied to bridges, storage tanks, and pipelines.

Quality Control

Our alkyd resins 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 against internal and customer specifications. Certificates of Analysis (COA) documenting these critical quality attributes are available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat sources and open flames. Under these conditions, the product is typically stable for 24 months from the date of manufacture.
