Description

Tung Oil/Rosin/Butylphenol/Formaldehyde/Pentaerythritol CAS NO 68122-57-6 is a specialized, high-performance phenolic resin derived from the condensation reaction of tung oil, rosin, butylphenol, formaldehyde, and pentaerythritol. This unique formulation is engineered to deliver exceptional durability, adhesion, and chemical resistance, making it a critical component in demanding industrial applications. It is primarily utilized by manufacturers in the coatings, adhesives, and ink industries seeking to enhance the performance and longevity of their final products.

Application

• High-Performance Industrial Coatings: As a key resin binder in marine, automotive, and heavy-duty maintenance paints for superior gloss, hardness, and corrosion resistance.
• Specialty Printing Inks: Used in formulations for metal decorating, overprint varnishes, and packaging inks to improve adhesion, rub resistance, and drying speed.
• Adhesives and Sealants: Serves as a tackifying and reinforcing agent in structural adhesives, pressure-sensitive tapes, and sealants for enhanced bond strength and thermal stability.
• Wood Finishes and Varnishes: Imparts excellent water resistance, durability, and a hard finish to wood coatings and furniture varnishes.
• Electrical Insulating Varnishes: Employed in wire enamels and insulating coatings for motors and transformers due to its good dielectric properties and thermal endurance.
• Rubber Compounding: Acts as a processing aid and reinforcing resin to improve the properties of rubber products.
