Table of Contents

Direct response to market needs & trends

Threaded connections in high-temperature-exposed applications like turbines or turbochargers require health-friendly lubrication to avoid seizing and to provide proper tightening torque.

MOLYKOTE® P-3700 Anti-Seize Paste

  • Provides controlled friction during assembly
  • Makes threaded connections simple to release after long periods of time at elevated temperatures
  • Is environmentally friendly and health-friendly – no hazard labeling and precautionary statements
  • Is free of intentional chromium ingredients
  • Significantly reduces formation of hexavalent chromium when used on alloys with high chromium content at T >300°C
  • Is free of any intentional calcium-based and magnesium-based ingredients

Performance advantages

  • Significantly reduces formation of hexavalent chromium when used on chromium containing alloys at >300°C
  • Wide service-temperature range: -30°C to 900°C
  • Excellent heat resistance: Fully functional anti-seizing property up to 900°C; higher temperatures were not tested
  • Provides controlled friction during assembly, supporting exact tensioning
