Tackle Hexavalent Chromium in turbines, turbochargers, and power plants with Molykote P-3700

Molykote P-3700 is a safe and sustainable choice for threaded connections in high-temperature environments such as turbines, turbochargers, and power plants. In this article, we delve into the new, unique, hazard-free innovation from Molykote, helping to ensure workplace safety and environmental sustainability.

Health & Safety in High-heat Environments

Some calcium-based lubricants pose potential health risks in high-heat applications due to hexavalent chromium. Also known as Cr(VI), hexavalent chromium is a toxic and carcinogenic compound and a concern in high-temperature lubrication applications. Under high temperatures, hexavalent chromium can form on certain threaded connections, particularly those in turbines and turbochargers, thus creating a health risk for maintenance workers and those exposed to direct contact.

Choosing Molykote P-3700

Selecting a lubricant with a hazard-free formula that doesn’t contain calcium or other hazardous compounds can nullify an otherwise severe risk. Molykote P-3700 is formulated for this purpose; the new lubricant is 100% hazard-free and formulated with no intentional calcium, lead, sulphur, chlorine, or fluorine, and thus no warning labels are required within its safety data sheet or packaging. And, whilst prioritising safety and sustainability, P-3700 doesn’t compromise on performance, delivering high-temperature durability and excellent anti-seize properties.

Key Features of Molykote P-3700:

  • Excellent anti-seize properties
  • Wide service temperature range: -30℃ to 900℃
  • Good fretting protection
  • High load-carrying capacity
  • Controlled friction
  • High purity
  • Release properties

When comparing Molykote P-3700 to its closest market competitor (one of few market lubricating pastes designed to combat the issue of hexavalent chromium in high temperature environments), you’ll find that this competitor product has a category two hazard-warning label, meaning the lubricant is considered toxic to aquatic organisms with longstanding and harmful effects. Molykote P-3700 is free of all hazard-warning labels for a far more ecologically conscious and safe choice. Plus, P-3700 will fit in with your safety and sustainability protocols for a swift and painless integration into your inventory. Not only is P-3700 safer, more sustainable, and kinder to the environment, but it’s also kinder to your finances, as despite being the best-in-class product, P-3700 is the more cost-effective choice.
