Description

2,2',6,6'-Tetrabromo Bisphenol A Diacrylate is a highly functionalized, brominated acrylate monomer that serves as a key reactive intermediate in advanced polymer synthesis. This compound matters for its ability to impart significant flame retardancy and enhanced thermal stability to final polymer networks, addressing critical safety and performance requirements. It is primarily needed by manufacturers in the electronics, aerospace, and specialty coatings industries seeking to develop high-performance, fire-resistant resins and adhesives.

Application

• As a reactive flame-retardant monomer in the production of epoxy acrylates and unsaturated polyester resins.
• In the formulation of fire-resistant coatings and inks for electronic components and circuit boards.
• As a cross-linking agent in the synthesis of specialty polymers for aerospace composite materials.
• In the manufacturing of high-refractive-index optical polymers and lenses.
• For the development of photopolymerizable resins used in 3D printing (stereolithography) requiring low flammability.
• As an additive or co-monomer in adhesives and sealants where enhanced fire safety is mandated.

Quality Control

Our 2,2',6,6'-Tetrabromo Bisphenol A Diacrylate is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for reactive monomer applications. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C/59-77°F) under an inert atmosphere (e.g., nitrogen) to prevent oxidation. Keep away from heat, sparks, and open flame. Isolate from strong oxidizing agents and bases.
