Description

2-[[Bis(2,3-Dibromopropoxy)Phosphinyl]Oxy]Ethyl Methacrylate is a specialized brominated phosphorus-containing methacrylate monomer designed to impart flame retardancy to polymeric materials. This compound matters for formulators seeking to enhance the fire safety of coatings, adhesives, and resins without compromising on mechanical properties. It is primarily needed by manufacturers in the polymer, electronics, and construction industries for producing flame-retardant acrylic resins, UV-curable systems, and specialty additives.

Application

• Flame-Retardant Acrylic Polymers: A key reactive monomer for synthesizing acrylic resins with inherent flame-retardant properties for coatings and films.
• UV-Curable Systems: Used in formulations for UV-curable inks, coatings, and adhesives where permanent flame retardancy is required.
• Electronic Encapsulants & Circuit Board Materials: Incorporated into resins for potting compounds and printed circuit board laminates to meet stringent UL-94 and other fire safety standards.
• Specialty Additives & Modifiers: Functions as a reactive additive to enhance the flame retardancy of other polymer systems like polyurethanes and unsaturated polyesters.
• Construction & Textile Coatings: Applied in fire-resistant coatings for fabrics, foams, and building materials.
