LR-H167 High Temperature Silicone Resin
Silfluo LR-H167 is a methyl phenyl silicone resin produced by polymerization of methyl and phenyl monomers with functional silane monomers, supplied at 70% solid content in toluene-containing solvent. The resin cures at ambient temperature and achieves full cure in 2 hours at 180°C.
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. Higher solid content (70% vs. 50% for LR-S165/LR-S161) reduces solvent load per unit of deposited resin solids.
