Description

Tung Oil, Linseed Oil, Phenol, Formaldehyde Polymer is a specialized phenolic resin derived from the co-condensation of phenol and formaldehyde with natural drying oils. This unique polymer combines the robust thermosetting properties of phenolic resins with the flexibility and drying characteristics imparted by tung and linseed oils. It is a critical material for formulators and manufacturers seeking high-performance, modified resins with enhanced compatibility and specific curing profiles. Key industries that utilize this polymer include coatings, adhesives, and composite materials.

Application

• Industrial Coatings and Varnishes: As a primary resin in high-durability, chemical-resistant coatings for metal, wood, and concrete.
• Friction Materials: As a binder in brake pads and clutch facings, providing thermal stability and binding strength.
• Adhesives and Sealants: Used in formulating high-strength, waterproof adhesives for construction and automotive applications.
• Foundry Core Binders: Serves as a binding agent in sand cores for metal casting, offering good collapsibility and strength.
• Abrasive Products: As a resin binder in grinding wheels and sandpaper, contributing to product integrity and performance.
• Electrical Laminates: Used in the production of composite laminates for electrical insulation components.
• Rubber Reinforcement: Acts as a tackifier and reinforcing resin in rubber compounding.
