Halogenated monomers are often clear or slightly colored liquids known for their high density and refractive index. These monomers incorporate halogens—such as chlorine, fluorine, or bromine—into their structure, which imparts excellent flame retardancy, chemical resistance, and adhesion to low-energy surfaces. These qualities make them ideal for specialty adhesives in aerospace, electronics, and construction where flame resistance or surface wetting is essential.
Though non-halogenated alternatives are often explored due to evolving regulatory trends, halogenated monomers remain critical where performance cannot be compromised. Formulators are encouraged to monitor local regulations, as product design can be influenced by application-specific compliance considerations.
