Features Of Arkema SR-423 NS Isobornyl Methacrylate Monomer

  1. High reactivity in free-radical polymerization processes due to low steric hindrance and optimized vinyl group accessibility.

  2. Excellent hydrophobicity and moisture resistance imparted by the rigid isobornyl moiety.

  3. Superior UV stability and weatherability compared to standard alkyl methacrylates.

  4. Low volatility and high boiling point, supporting safer handling and reduced VOC emissions.

  5. Enhanced hardness and scratch resistance in cured acrylic coatings and adhesives.

Typical Applications Of Arkema SR-423 NS Isobornyl Methacrylate Monomer

  1. UV-curable industrial coatings for metal and plastic substrates.

  2. High-performance pressure-sensitive adhesives requiring elevated tack and shear strength.

  3. Optical-grade clear resins for LED encapsulation and lens materials.

  4. Hard, abrasion-resistant topcoats for automotive refinish and architectural applications.

  5. Functional monomer in specialty acrylic copolymers for optical films and display components.
