Perfluoropolyether Methacrylate

Full name: Perfluoropolyether methacrylate Abbreviation: PFPE-MAA / Fluorinated polyether acrylic ester CAS: No fixed CAS (polymer monomer, molecular weight is not fixed) Molecular formula: [CF(CF₃)CF₂O]ₙ-CH₂-O-COC(CH₃)=CH₂ Appearance: Colorless to pale yellow transparent viscous liquid Molecular weight: Common specifications include 1000/2000/3000/4000 etc. Purity: ≥98% (HPLC) Structural characteristics: One end is a perfluoropolyether (PFPE) chain segment (ultra-low surface energy, hydrophobic and oleophobic), and the other end is a methacrylate double bond (can undergo UV / heat / free radical polymerization) Core properties ✅ Ultra-low surface energy: Strong hydrophobic and oleophobic, anti-fingerprint, anti-stains ✅ High stability: Resistant to acids, alkalis, weathering, heat, oxidation ✅ Reactivity: The double bond can participate in UV curing / free radical copolymerization, compatible with acrylic, epoxy, polyurethane systems ✅ Low refractive index (1.30–1.35), good optical transparency ✅ Environmentally friendly: Does not contain long-chain perfluoroalkyl (PFOA/PFOS), can replace traditional fluorine-containing monomers Main applications UV curing coatings: Anti-fingerprint for mobile phones / tablets, optical AR/AS coating, anti-wetting layer for glasses / lenses Polymer modification monomers: Copolymerized with acrylic, polyurethane, epoxy to enhance surface anti-fouling, wear resistance, and release performance Fluorinated surfactants: Low foam, high wetting, resistant to acids and alkalis, used in coatings, inks, cleaning aids High-end release agents / anti-stick coatings: Mold, rubber / plastic processing, release film Electronics / semiconductors: Moisture protection for wafers / substrates, low dielectric materials, photomask additives
