Description

Formaldehyde, Polymer With Butylphenol And Phenol (CAS NO 51732-68-4) is a phenolic resin intermediate, a key building block for high-performance thermoset polymers. This compound matters for its ability to impart excellent thermal stability, chemical resistance, and mechanical strength to final cured materials. It is primarily needed by manufacturers in the coatings, adhesives, and composite industries seeking durable and reliable polymeric matrices.

Application

• Production of phenolic resins for high-temperature molding compounds.
• Key intermediate in formulating industrial coatings and corrosion-resistant paints.
• Manufacture of adhesives and bonding agents for wood, automotive, and aerospace applications.
• Component in friction materials such as brake pads and clutch facings.
• Used in foundry resins for sand casting in metalworking.
• Base material for electrical laminates and insulating varnishes.
• Formulation of abrasive wheels and grinding tools.
