Description

Styrene, Soya Oil, Phthalic Anhydride, Glycerin, Tung Oil Polymer CAS NO 68783-94-8 is a specialized polymeric resin synthesized from a blend of styrene, modified vegetable oils, and anhydride compounds. This engineered material is valued for its ability to impart excellent film-forming properties, chemical resistance, and durability to final products. It is a critical component for manufacturers in the coatings, adhesives, and composite materials industries seeking high-performance, sustainable-enhancing resin solutions.

Application

• Industrial Coatings & Paints: Used as a primary resin or modifier in alkyd paints, marine coatings, and protective industrial finishes for enhanced water resistance and gloss.
• Adhesives & Sealants: Serves as a key polymeric binder in construction adhesives, automotive sealants, and pressure-sensitive tapes, providing strong adhesion and flexibility.
• Composite Materials: Acts as a matrix resin or cross-linking agent in fiberglass-reinforced plastics (FRP) and other composite systems.
• Printing Inks: Utilized in the formulation of overprint varnishes and specialty inks to improve rub resistance and drying characteristics.
• Wood Finishes: Incorporated into varnishes and lacquers for furniture and flooring to deliver a durable, protective topcoat.
• Electrical Insulation: Employed in potting compounds and insulating varnishes for electrical components due to its dielectric properties.

Quality Control

Our Styrene, Soya Oil, Phthalic Anhydride, Glycerin, Tung Oil Polymer is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters including viscosity, acid value, solids content, and color 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, and well-ventilated area at room temperature (15-25°C/59-77°F). Keep away from strong acids, organic solvents, and sources of ignition. As the product is easily oxidized, containers should be kept tightly sealed when not in use to minimize exposure to air.
