Description

2,2',6,6'-Tetrabromo Bisphenol ''A'' Dimethacrylate CAS NO 42146-13-4 is a high-purity, brominated dimethacrylate monomer. This compound is valued for its ability to impart significant flame retardancy and enhanced thermal stability to polymer matrices. It is primarily sought by manufacturers in the electronics, aerospace, and specialty coatings industries for producing high-performance, fire-resistant resins, adhesives, and composite materials.

Application

• As a reactive flame-retardant monomer in the synthesis of specialty acrylic and methacrylic resins.
• Manufacturing of printed circuit boards (PCBs) and electronic encapsulants requiring high flame retardancy (e.g., UL 94 V-0 rating).
• Production of fire-resistant adhesives, sealants, and gel coats for aerospace and marine applications.
• Formulation of halogenated unsaturated polyester resins (UPR) for composite materials.
• Key intermediate in the synthesis of advanced polymers for optical fibers and lenses with low flammability.
• Use in coatings and inks where enhanced fire safety properties are critical.
