Technical Data Sheet
Typical technical characteristics and operating guidance for MOLY Anti-Seize MP40.
| Property | Test Method | Typical Value |
|---|---|---|
| Operating Temperature | — | -40°C to +450°C (two-stage: organo-clay grease base / MoS2 solid film) |
| MoS2 Content | — | 40% |
| NLGI Grade | ASTM D217 | Paste |
| Base | — | Organo-clay grease |
| Water Resistance | — | Excellent |
| Appearance | Visual | Dark gray/black paste |
The organo-clay grease base lubricates at moderate temperatures; as its oil phase volatilises at elevated temperature the MoS2 film remains on the thread and continues to protect the joint up to 450°C.
Operating Parameters
Temperature Range
-40°C to +450°C continuous (MoS2 film above base oil volatilisation)
Viscosity Grade

Service Life
Condition dependent
Below the base oil volatilisation point the organo-clay grease supplies conventional lubrication and corrosion protection. Above it the MoS2 particles stay on the mating surfaces as a dry film, which is what keeps MP40 effective where an ordinary grease would carbonise.
Frequently Asked Question
Why does MP40 still protect threads after the grease has burned off?
MP40 contains 40% molybdenum disulfide. The organo-clay grease base lubricates at normal temperatures; once its oil phase volatilises at high temperature, the MoS2 film stays on the mating surfaces and continues to prevent galling and seizure up to 450°C.
Consistent Performance
Formulations are developed for stable viscosity, wear protection and contamination control across the stated operating range.
Optimized Formulation
Engineered for stable film strength and anti-wear performance, supporting longer service intervals where operating conditions and oil analysis allow.
Quality Assured
Manufactured under ISO 9001:2015 quality management system with full batch traceability and certificate of analysis.
Application Guide
Step-by-step instructions for optimal use of MOLY Anti-Seize MP40 in Oil & Gas applications.
Preparation
Ensure the application surface is clean, dry, and free from contaminants. Remove any existing lubricant residues using appropriate cleaning agents. For Drill pipe threads applications, verify equipment is at operating temperature.
Application Method
Apply MOLY Anti-Seize MP40 using standard industrial equipment. For grease products, use automatic lubrication systems or manual grease guns. For liquid lubricants, ensure proper filling procedures and avoid contamination during transfer.
Recommended Dosage
Follow OEM recommendations for fill quantities. For Oil & Gas applications, typical re-lubrication intervals range from 1,000 to 5,000 operating hours depending on conditions. Monitor performance and adjust intervals based on actual operating parameters.
Performance Monitoring
Regularly inspect lubricant condition and equipment performance. Check for signs of degradation, contamination, or unusual wear. Schedule oil analysis every 6 months for critical applications to optimize maintenance intervals.
Storage Recommendations
- Store in a cool, dry place between 5°C and 35°C
- Keep containers sealed when not in use
- Avoid direct sunlight and moisture exposure
- Shelf life: 5 years from manufacture date when stored properly
Safety Information
- Refer to Safety Data Sheet (SDS) before use
- Use appropriate PPE: gloves and safety glasses
- Ensure adequate ventilation in application area
- Dispose of used lubricant according to local regulations
