Description

Formaldehyde, Polymer With 4,4'-(1-Methylethylidene)Bis[Phenol] And Phenol is a high-performance phenolic resin intermediate, also known as a novolac-type phenolic resin. This compound is critical for producing durable, heat-resistant, and chemically stable thermoset plastics and coatings. It is essential for manufacturers in the electronics, automotive, and industrial adhesive sectors seeking reliable raw materials for advanced composite materials.

Application

• Epoxy Resin Curing Agent: A key hardener for epoxy resin systems, imparting excellent thermal and mechanical properties for composites and laminates.
• Molding Compounds: Used in the production of phenolic molding powders for electrical components, automotive parts, and appliance handles.
• Friction Materials: Serves as a binder in brake pads and clutch facings, providing necessary thermal stability and wear resistance.
• Foundry Resins: Acts as a binder in sand casting processes for metal foundries to create precise and strong molds and cores.
• Industrial Adhesives & Coatings: A fundamental component in high-performance adhesives, abrasives, and protective coatings.
• Printed Circuit Board Substrates: Used in the formulation of resins for copper-clad laminates (CCL) in electronics.
