LR-M124 Acrylic Modified Organic Silicone Resin

Silfluo LR-M124 series is produced by hydrolyzing methyl and phenyl silane monomers to silanol, then copolymerizing with specific acrylic monomers. The resulting silicone-acrylic hybrid matrix combines the gloss, adhesion, and low-temperature curability of acrylic resins with the heat resistance and weatherability of silicone. The series is supplied at 50% solid content in toluene/xylene solvent blend and is capable of both ambient two-component curing and forced thermal curing.

Use reference of Acrylic Modified Organic Silicone Resin LR-M124


  • Ambient Curing (2K System): Formulate with isocyanate hardeners such as Bayer 3390 or N75 at 10-20% addition based on total resin weight for room-temperature cure.

  • Forced Thermal Curing: Bake at 180°C for 1 hour. Compatible with amino resins to accelerate and enhance the thermal cure process.

  • Safe Handling and Ventilation: This product contains toluene, xylene, and other flammable, volatile solvents. Explosion-proof ventilation must be maintained during processing. Keep away from open flames, ignition sources, and static electricity sources. Follow occupational safety protocols and use appropriate personal protective equipment (PPE).
