Description

Phenol, 4,4-(1-Methylethylidene)Bis-, Polymer With (Chloromethyl)Oxirane, Methyloxirane And Oxirane CAS NO 68123-18-2 is a specialized epoxy-functional phenolic resin, commonly known as a phenolic novolac epoxy resin. This advanced polymer is engineered to deliver exceptional thermal stability, chemical resistance, and strong adhesion properties, making it a critical component in high-performance formulations. It is primarily utilized in industries requiring durable, cross-linked polymer matrices, such as advanced composites, high-temperature adhesives, and protective coatings.

Application

• Advanced Composite Materials: As a matrix resin for fiber-reinforced composites in aerospace, automotive, and sporting goods for superior strength-to-weight ratios.
• High-Temperature Adhesives & Sealants: Formulating adhesives for metal bonding, electronics assembly, and automotive applications where thermal endurance is critical.
• Protective & Corrosion-Resistant Coatings: Serving as a base resin in industrial, marine, and pipeline coatings that require excellent chemical and moisture resistance.
• Electrical Laminates & Encapsulation: Used in the production of printed circuit boards (PCBs) and for encapsulating electronic components due to its good electrical insulation properties.
• Molding Compounds: A key ingredient in compression and transfer molding compounds for electrical and automotive components.
• Friction Materials: Employed in formulations for brake pads and clutch facings to enhance thermal stability and wear resistance.
