Description

Tung Oil, Polymer With o-Cresol And Formaldehyde is a specialized phenolic-modified tung oil resin, a high-performance polymer synthesized from natural tung oil, o-cresol, and formaldehyde. This engineered resin offers a unique combination of chemical resistance, flexibility, and adhesion derived from its modified phenolic and tung oil backbone. It is a critical raw material for formulators in the coatings, adhesives, and composite industries seeking to enhance product durability and performance. The CAS Registry Number for this compound is 67746-22-9.

Application

• High-Performance Industrial Coatings: Used as a binder or modifier in corrosion-resistant primers, marine paints, and chemical-resistant topcoats.
• Adhesives and Sealants: Serves as a tackifying and reinforcing resin in structural adhesives, rubber-based sealants, and pressure-sensitive adhesives.
• Friction Materials: Acts as a binder resin in brake linings, clutch facings, and other composite friction materials requiring thermal stability.
• Foundry Core Binders: Utilized as a binder resin in shell molding and core-making processes for metal casting.
• Electrical Insulating Varnishes: A key component in wire enamels and impregnating varnishes for motors and transformers.
• Rubber Compounding: Functions as a processing aid and reinforcing resin to improve the properties of rubber compounds.
• Printing Inks: Used in specialty printing inks requiring excellent adhesion and resistance properties.

Quality Control

Our Tung Oil, Polymer With o-Cresol And Formaldehyde is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance and meets the specifications required for industrial applications. Certificates of Analysis (COA) documenting key parameters such as viscosity, softening point, and non-volatile content are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and open flame. 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 or changes in viscosity.
