MOLYKOTE® 112 is an NLGI Grade 3 silicone-based compound with silica thickener used in applications that require high mechanical stability.
MOLYKOTE® 112, a high-performance lubricant and sealant, is a silicone-based compound that provides protection and lubrication in applications with high temperatures and mechanical shear. MOLYKOTE® 112 high-performance sealant exhibits excellent resistance to water, oil, ozone, and harsh chemicals and is well suited for withstanding difficult environments.
MOLYKOTE® 112 sealant and lubricant is nonmelting silicone and serves exceedingly well as an O-ring and valve sealant in a broad temperature range of −40°F to 450°F (−40°C to 232°C).
