Description
Molykote P-3700 is a highly pure paste with solid lubricants designed for threaded connections operating in extreme temperature conditions. This paste, based on mineral oil and special solid lubricants, is formulated without the intentional addition of calcium, lead, nickel, sulfur, chlorine, or fluorine, making it ideal for applications requiring minimal contamination with impurities and protection against metal embrittlement.
Composition and functional properties:
- High purity: Regularly monitored impurity content (sulfur, calcium, total halogens) for safe use on sensitive materials.
- Temperature resistance: Stable function of solid lubricants in the range from -30 °C to +900 °C.
- Chemical compatibility: Specifically designed for alloys with high chromium content and stainless steel (A2-70, 1.4301).
- Environmental profile: Does not contain intentionally added PTFE or PFAS substances.
- Friction control: Ensures defined and stable friction values during assembly to achieve precise pre-tensioning of the joint.
- Anti-seize effect: Allows for easy disassembly of joints even after long-term exposure to temperatures above 500 °C without damaging the thread.

Application area:
The paste is suitable for lubricating screws, nuts, and pins in industrial equipment exposed to high temperatures. It is particularly recommended for connections made of stainless steel and high-alloy steels in energy (turbines), petrochemicals, and heavy machinery, where the absence of nickel and sulfur is required.
Application instructions:
Before application, thoroughly clean and degrease the contact surfaces. Use a wire brush to remove rust or residues of old lubricants. Apply the paste in an even layer to ensure the entire surface of the thread is covered. Do not mix the product with other lubricating greases or pastes. Store in a closed container at temperatures between 0 °C and 35 °C.
