LR-M123 Epoxy Modified Silicone Resin
Silfluo LR-M123 series are epoxy-modified silicone resins supplied at 50% solid content in xylene-containing solvent, combining the thermal stability and weatherability of silicone with the adhesion, chemical resistance, and crosslink density of epoxy. The two grades differ primarily in epoxy value and performance balance: LR-M123-4 carries a higher epoxy value (0.06–0.16), delivering superior corrosion resistance at the cost of slightly reduced continuous high-temperature endurance; LR-M123-6 carries a lower epoxy value (0.02–0.07), shifting the balance toward higher thermal performance. Both grades support room-temperature two-component cure with isocyanate hardeners and forced thermal cure at 180°C.
