Used as a reactive brominated flame retardant in epoxy and unsaturated polyester resins. It is particularly effective in printed circuit boards and electrical laminates where high thermal stability and flame resistance are required. The compound participates in polymerization, becoming chemically bound to the resin matrix, which enhances flame retardancy without leaching. Offers good compatibility with other brominated systems and maintains mechanical and electrical properties of the final product. Suitable for applications meeting stringent fire safety standards such as UL94 V-0.
