What is Hexafluoroisopropyl acrylate?
Hexafluoroisopropyl acrylate (CAS 2160-89-6) is a fluorinated acrylic monomer that introduces extreme hydrophobicity, chemical resistance, and low surface energy into polymer systems.
Where is Hexafluoroisopropyl acrylate used?
- Specialty coatings, optical materials, and high-performance polymer formulations: reactive building block where standard acrylates fall short on durability
- Electronics and photonics: UV-curable resins and optical coatings targeting low refractive index and moisture resistance
- Aerospace and defense: films resisting fuels, solvents, and aggressive atmospheric conditions
- Fluoropolymer synthesis: comonomer tuning surface energy and chemical resistance of specialty membranes and release coatings
- Anti-fouling and hydrophobic surface treatments give substrates durable, low-adhesion finishes.
Commercial specifications
- Inhibitor added to prevent premature polymerization during storage and transport
- Purity commonly 97% upward
