Description

Tung-Linseed Oil/Rosin/Phenol/Formaldehyde/Pentaerythritol CAS NO 68153-92-4 is a specialized, high-performance modified phenolic resin, engineered through the reaction of tung oil, linseed oil, rosin, phenol, formaldehyde, and pentaerythritol. This unique formulation is critical for producing durable, flexible, and chemically resistant coatings and adhesives that outperform standard phenolic resins. It is an essential raw material for manufacturers in the protective coatings, printing inks, industrial adhesives, and composite materials sectors seeking enhanced performance characteristics.

Application

• High-Performance Industrial Coatings: Used as a binder in corrosion-resistant primers and finishes for marine, automotive, and heavy-duty equipment.
• Specialty Printing Inks: Serves as a key resin component in heat-set, lithographic, and metal-decorating inks for superior gloss and adhesion.
• Structural and Laminating Adhesives: Provides excellent bonding strength and flexibility in wood, paper, and metal laminate adhesives.
• Composite Material Binders: Utilized in fiberglass-reinforced plastics (FRP) and friction materials (e.g., brake linings) for thermal stability.
• Electrical Insulating Varnishes: Formulated into wire enamels and impregnating resins for motors and transformers.
• Rubber Compounding and Tackifiers: Acts as a processing aid and tackifier to improve the properties of rubber products.

Quality Control

Our modified phenolic resin is manufactured under a stringent quality management system. Each batch undergoes rigorous testing for key parameters including viscosity, acid value, color, and non-volatile content to ensure consistent performance and batch-to-batch reliability. Certificates of Analysis (COA) documenting full specifications are available upon request to support your quality assurance protocols.

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 acids and organic solvents. Ideal storage temperature is between 15°C and 25°C (59°F and 77°F). Keep containers tightly sealed when not in use to prevent skin formation and maintain product integrity.
