Description

Tall Oil/Phthalic Anhydride/Pentaerythritol/Ethyleneglycol CAS NO 68015-03-2 is a specialized polymeric resin derived from the co-esterification of tall oil fatty acids, phthalic anhydride, pentaerythritol, and ethylene glycol. This versatile alkyd-type resin is engineered to provide excellent film-forming properties, adhesion, and chemical resistance, making it a critical intermediate for high-performance coatings and adhesives. It is primarily sought by manufacturers in the protective coatings, industrial paints, printing inks, and adhesive formulation sectors who require durable, weather-resistant binders.

Application

• Protective & Marine Coatings: Serves as a primary binder in anti-corrosive primers and topcoats for metal structures, ships, and offshore platforms, offering excellent resistance to water and salt spray.
• Industrial Enamels & Paints: Used in the formulation of air-drying or baking enamels for machinery, agricultural equipment, and appliances, providing a hard, glossy, and durable finish.
• Printing Inks: Acts as a resinous component in specialty printing inks, contributing to gloss, rub resistance, and adhesion on various substrates.
• Adhesives & Sealants: Functions as a tackifying and reinforcing resin in solvent-based or hot-melt adhesive systems, enhancing bond strength and flexibility.
• Wood Finishes: Employed in varnishes and wood stains to enhance grain appearance, provide a protective layer, and improve durability.
• Primers: Formulated into high-build primers for metals and wood, offering superior surface wetting and intercoat adhesion.

Quality Control

Our Tall Oil/Phthalic Anhydride/Pentaerythritol/Ethyleneglycol resin is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance characteristics such as acid value, viscosity, solids content, and color. Certificates of Analysis (COA) documenting these key parameters 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, well-ventilated area away from heat sources and incompatible materials such as strong bases and oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Due to its organic solvent content and potential for oxidation, containers should be kept tightly sealed when not in use to prevent solvent loss and skin formation.
