Description

Cresol-Formaldehyde Resin CAS NO 9016-83-5 is a synthetic phenolic resin produced by the condensation reaction of cresol isomers with formaldehyde. This thermosetting polymer is valued for its excellent heat resistance, chemical stability, and strong adhesive properties. It is a critical raw material for manufacturers in the coatings, adhesives, and friction materials industries seeking durable and high-performance polymer components.

Application

• Friction Materials: As a key binder in brake pads, clutch facings, and other friction composites, providing thermal stability and structural integrity.
• Industrial Adhesives & Bonding Agents: Used in high-strength adhesives for wood, abrasive grains (in grinding wheels), and foundry sand molds.
• Protective Coatings & Varnishes: Imparts chemical and moisture resistance in industrial primers, marine coatings, and wire enamels.
• Rubber Compounding: Acts as a tackifier and reinforcing resin to improve the hardness and processing of rubber products.
• Printing Inks: Employed in specialty inks to enhance gloss, drying speed, and resistance properties.
• Electrical Insulation: Used in the formulation of laminates and potting compounds for electrical components.
