LR-S161 Self-drying Silicone Resin
Silfluo LR-S161 is an ambient-curing silicone resin produced by copolymerization of methyl, phenyl, and functional silane monomers, supplied as a 50% solids solution. The resin crosslinks at room temperature without oven baking, and achieves full cure in 1 hour at 180°C when accelerated cure is applied.
The methyl phenyl siloxane backbone provides continuous heat resistance, surface hardness, corrosion resistance, and gloss retention in the cured film. When formulated with leafing aluminum powder at a 4:1 resin-to-pigment ratio, the cured coating withstands 500 ± 10°C for 3 hours without peeling, cracking, or blistering.
