CSL Silicones CSL841 Non Curing Silicone Grease Compound

CSL Silicones CSL841 Non Curing Silicone Grease Compound is a non-curing, general-purpose, dielectric silicone grease compound. It is a grease-like material that is ideally suited for lubricating, waterproofing, corrosion protection, mold release, and insulating. It is moisture-resistant and retains its consistency and properties over a temperature range of -76°F to 392°F. CSL841 is a non-toxic, non-melting, highly water repellant silicone grease resistant to oxidation. Practically nonvolatile, CSL841 is also odorless, resistant to a wide range of chemicals, and has excellent dielectric properties. CSL841 has excellent thermal and oxidative stability and low surface tension.
