Epoxy Modified Silicone Resin LR-M123

The product has excellent resistance to both high and low temperatures, along with hydrophobicity and moisture resistance. It also possesses strong electrical insulation properties, as well as resistance to arc and corona discharge, and outstanding weather durability. Additionally, it demonstrates good chemical stability and corrosion resistance.

Compared to LR-M123-6, LR-M123-4 offers superior corrosion resistance but has slightly lower high-temperature resistance.

Use reference of Epoxy Modified Silicone Resin LR-M123

  • Cures at room temperature with a two-component system, combined with an isocyanate curing agent such as Bayer 3390, N75, etc., at an addition rate of 10–20% of the total resin.

  • For high-temperature curing, heat to 180°C and maintain for one hour. It can also be used with amino resin to reduce curing time.

  • The diluent used in this product must be free of water, acids, alkalis, amines, and similar compounds, as these may negatively impact adhesion, drying, and other film properties.

  • This product contains xylene and other flammable, volatile solvents. Ensure proper ventilation during processing. Take precautions against fire, static electricity, and ignition sources. Operators should prioritize safety measures and wear appropriate protective equipment.
