Description

Isononanoic Acid,Trimethylolethane,Phthalic Anhydride Alkyd Resin,4-tert-Butylbenzoic Acid Modified is a specialized, high-performance alkyd resin designed for demanding industrial coating applications. This modified resin offers a superior balance of hardness, flexibility, and chemical resistance, making it a critical component for formulating durable finishes. It is primarily used by manufacturers in the protective coatings, automotive refinish, and industrial maintenance paint sectors who require reliable performance under harsh environmental conditions. CAS No. 67989-05-3.

Application

• High-Performance Industrial Coatings: Formulation of air-drying or force-dried enamels for machinery, agricultural equipment, and structural steel.
• Automotive Refinish Paints: Used in primer-surfacers and topcoats requiring excellent sandability, adhesion, and gloss retention.
• Protective & Maintenance Coatings: Base for anti-corrosive primers and finishes used in marine, offshore, and infrastructure projects.
• General Metal Finishes: Manufacturing of coatings for metal furniture, appliances, and other metal substrates.
• Specialty Resin Modifications: Acts as a modifying resin to enhance specific properties like drying time, hardness, or solubility in other coating systems.

Quality Control

Our alkyd resins are manufactured under strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including viscosity, acid value, color, and solids content. Certificates of Analysis (COA) documenting these specifications 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, and well-ventilated area away from heat sources and open flames. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent skinning and maintain product integrity.
