Product Introduction
Engineered for harsh environments, this compound delivers reliable performance in dynamic sealing and lubrication applications. Its silicone oil formulation maintains stability under high pressure, vacuum, and wet conditions while exhibiting compatibility with most plastics and elastomers to prevent material degradation.
Enhanced Properties
- Beyond core properties, Molykote 111 demonstrates minimal oil bleed (≤0.5% after 24h at 200°C) and low evaporation loss (≤2.0%), ensuring long-term efficacy.
- It resists mineral/vegetable oils and dilute acids/alkalines, but is incompatible with liquid oxygen (LOX) systems.
Application Scenarios
- Widely used in control/pressure plug valves, water softeners, and vacuum seals (e.g., shipboard meters, underground electrical connections).
- As an anti-stick sealant for transformer gaskets, it prevents metal adhesion while resisting weathering.
- Suitable for rubber/plastic O-rings, gaskets, and dash pot damping.
