Description

Formaldehyde, Polymer With 4-(1,1-Dimethylethyl)Phenol, 4-(1,1-Dimethylpropyl)Phenol, Methyloxirane And Oxirane CAS NO 68155-80-6 is a specialized phenolic-modified epoxy novolac resin, engineered to deliver enhanced thermal stability and chemical resistance. This polymer is critical for formulators requiring high-performance thermoset materials with superior mechanical properties and adhesion. It is primarily targeted for advanced industrial applications in the electronics, aerospace, and high-temperature composite manufacturing sectors.

Application

• Advanced Composite Matrices: Used as a high-performance resin matrix for carbon fiber and fiberglass composites in aerospace and automotive structural components.
• Electronic Encapsulation & Underfill: Serves as a key ingredient in epoxy molding compounds (EMCs) and underfill materials for semiconductor packaging, offering excellent moisture resistance and low thermal expansion.
• High-Temperature Adhesives: Formulated into structural adhesives and pastes for bonding metals, ceramics, and other substrates in demanding environments.
• Protective & Insulating Coatings: Utilized in industrial and electrical coatings that require long-term durability against chemicals, heat, and corrosion.
• Laminates for Printed Circuit Boards (PCBs): Acts as a resin component in multilayer PCB laminates, providing good dielectric properties and thermal reliability.
• Friction Materials & Abrasives: Incorporated as a binder in brake pads, clutch facings, and grinding wheels due to its thermal stability.
