LR-M125 Alkyd Modified Silicone Resin

Silfluo LR-M125 is an alkyd-modified silicone resin produced by copolymerization of silanol (derived from hydrolysis of methyl and phenyl silane monomers) with alkyd resin, supplied at 50% solid content. The combined silicone-alkyd matrix provides heat resistance, weather resistance, and substrate adhesion, with ambient-temperature curing capability, hardness, pigment dispersion, and flexibility in the cured film.

When formulated with leafing aluminum powder at a 4:1 resin-to-pigment ratio, the cured coating withstands 400 ± 10°C for 4 hours without peeling, cracking, or blistering.

Applications of Alkyd Modified Silicone Resin LR-M125


  • Heat-Resistant and Weather-Resistant Coatings

    Used for formulating heat-resistant coatings for continuous service up to 300°C and weather-resistant paints.

  • Electrical Insulation

    Used in the formulation of Class H silicone-based insulating varnishes.


Use Reference of Alkyd Modified Silicone Resin LR-M125


  • Ambient Cure (Two-Component): Cure at room temperature by formulating as a 2K system with isocyanate hardener (e.g., Bayer 3390, N75) at 10–20% hardener addition based on total resin weight.

  • Forced Thermal Cure: Fully cure by baking at 180°C for 1 hour. Compatible with amino resins to accelerate thermal cure.

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


Package & Storage of Alkyd Modified Silicone Resin LR-M125


  • In 200kg drum.

  • Keep in a cool, dry, and well-ventilated environment, strictly avoiding direct sunlight, acids, and alkalis. The shelf life is 6 months from the date of manufacture when stored in original unopened containers (material can still be utilized if it passes quality inspection after the expiration date). Classified and transported as a hazardous substance (flammable liquid).
