Description

Cashew, Nutshell Liq., Polymer With Formaldehyde is a thermosetting phenolic resin derived from cashew nutshell liquid (CNSL) and formaldehyde. This specialized polymer is valued for its excellent chemical resistance, heat stability, and durable, cross-linked network structure. It is primarily used in industrial applications requiring robust, protective coatings, adhesives, and friction materials. The CAS number for this compound is 68583-07-3.

Application

• Friction Materials: A key binder resin in the manufacture of automotive and industrial brake linings and clutch facings, providing thermal stability and wear resistance.
• Protective Coatings: Formulated into high-performance industrial paints, varnishes, and marine coatings that offer superior resistance to chemicals, solvents, and moisture.
• Adhesives & Laminates: Used in the production of phenolic adhesives for wood composites, plywood, and abrasive products like grinding wheels and sandpaper.
• Rubber Compounding: Acts as a tackifier and reinforcing agent in rubber formulations, improving adhesion and mechanical properties.
• Foundry Resins: Employed as a binder in shell molding and core-making processes for metal casting.
• Electrical Insulation: Utilized in the production of laminates for printed circuit boards and other electrical insulating components due to its dielectric properties.
