Molykote 111 Compound 400G Silicone Grease

MOLYKOTE Silicone Grease for Sealing, Lubrication and Protection

MOLYKOTE 111 Silicone Grease is used to seal, lubricate and protect a wide range of parts such as rubber O-rings, valves, seals, fittings and plastic components. This makes MOLYKOTE 111 Compound the ideal choice as a professional silicone grease for industrial maintenance, HVAC systems, potable water pipes, pumps, valves, electrical connections, and process equipment.

With excellent water and chemical resistance, the grease remains effective even in harsh environments; from deep-freeze installations to hot production lines.

Benefits of MOLYKOTE 111 Compound Grease

• Long-lasting performance: Provides lasting lubrication and sealing, even under varying temperature and humidity conditions.

• Water and corrosion resistance: Maintains performance even in wet or damp conditions.

• Elastomer compatibility: Safe for use on rubbers, O-rings, and plastics.

• Wide range of applications: Suitable for industrial machinery, pneumatic systems, hydraulics, pumps, valves, and more.

• Neutral effect: Electrically non-conductive, suitable for applications where insulation is important.

• Washout resistance: Stays in place without washing out or thinning.

How to use MOLYKOTE Silicone Grease 111?

For best results, it's important to apply MOLYKOTE 111 Silicone Grease correctly. Because MOLYKOTE 111 Silicone Grease comes in a 400g cartridge, you'll need a caulking gun to use it properly. Always first ensure the surface is clean, dry, and free of dust, oil, or old grease residue.

Then, apply MOLYKOTE 111 Compound 400g in the cartridge using a caulking gun to the gasket, O-ring, or surface you want to protect. Use just enough to create a film; more grease doesn't always mean a better seal.

For valves or seals, you can spread the grease on moving parts to ensure smooth operation and corrosion protection. For rubbers or O-rings in contact with gases or liquids, lightly lubricate the ring to ensure it fits smoothly into the seat and does not dry out.
