Graphite Suspension FAQ
Q: What makes Graphite Suspension different from regular graphite lubricants?
A: Graphite Suspension features a proprietary formulation with optimized particle size distribution and superior dispersion technology. Unlike conventional graphite lubricants that may settle quickly, our suspension maintains consistent performance throughout its service life. The advanced carrier system ensures maximum graphite particle adhesion to surfaces while allowing easy application.
Q: Is Graphite Suspension compatible with other lubricants?
A: While Graphite Suspension can be used alongside some lubricants, we recommend consulting our technical team before mixing with other products. Our suspension is compatible with most mineral oils but may react with certain synthetic base stocks. For best results, surfaces should be thoroughly cleaned before applying Graphite Suspension as a standalone solution.
Q: How should Graphite Suspension be stored for maximum shelf life?
A: Store Graphite Suspension in its original container at temperatures between 5°C and 30°C (41°F to 86°F). Keep containers tightly sealed and away from direct sunlight. Under proper storage conditions, our product maintains its effectiveness for up to 24 months from production date. Avoid freezing as this may affect particle dispersion.

More Graphite Suspension Questions
Q: Can Graphite Suspension be used in food processing equipment?
A: Yes, we offer a special NSF H1-registered food-grade version of Graphite Suspension that complies with FDA 21 CFR §178.3570 for incidental food contact. This formulation uses ultra-pure graphite and food-approved carrier fluids while maintaining the same performance characteristics as our industrial-grade product.
Q: What application methods work best for Graphite Suspension?
A: Graphite Suspension can be applied through various methods including brush application, spray systems (airless preferred), drip feed systems, or automated lubrication systems. For best results, apply a thin, even coat to clean, dry surfaces. Heavily worn components may benefit from multiple thin applications rather than a single thick coat.
Q: Does Graphite Suspension conduct electricity?
A: Yes, Graphite Suspension maintains the conductive properties of graphite, making it suitable for applications requiring electrical conductivity while needing lubrication. The typical surface resistivity ranges from 10-3 to 101 ohm-cm depending on film thickness and application method.
Safety and Environmental Information
Graphite Suspension meets or exceeds international safety and environmental standards:
- REACH compliant
- RoHS compliant
- Non-hazardous according to OSHA 29 CFR 1910.1200
- Biodegradability >60% in 28 days (OECD 301B)
- Contains no heavy metals or restricted substances
Graphite Suspension Technical FAQ
Q: What is the recommended surface preparation before applying Graphite Suspension?
A: For optimal performance, surfaces should be cleaned of all existing lubricants, dirt, and oxidation. We recommend using a solvent degreaser followed by thorough drying. Light abrasion (sandblasting or scuffing) can improve adhesion on smooth surfaces. In high-temperature applications, a brief heat cure (150-200°C for 30 minutes) helps establish the graphite film.
Q: How often should Graphite Suspension be reapplied?
A: Reapplication intervals depend on operating conditions. Under normal loads at moderate temperatures (below 300°C), Graphite Suspension typically lasts 3-6 months. In extreme conditions (high loads, temperatures above 400°C, or exposure to aggressive chemicals), more frequent applications every 1-3 months may be necessary. Monitor performance and reapply when friction increases or lubrication appears insufficient.
Q: Can Graphite Suspension be used in vacuum applications?
A: Yes, Graphite Suspension performs exceptionally well in vacuum environments up to 10-6 torr. The formulation has exceptionally low outgassing properties (total mass loss <1%) and doesn't contaminate sensitive vacuum systems. We offer a special vacuum-grade version with reduced volatile content for critical space and semiconductor applications.
