MOLYKOTE® P-3700 Anti-Seize Paste

A direct response to market needs and trends

Threaded connections in high-temperature applications, such as turbines or turbochargers, require proper lubrication to prevent seizure and provide adequate tightening torque.

 

MOLYKOTE® P-3700 Anti-Seize Paste

 

  • Ensures controlled friction during assembly
  • Facilitates loosening of threaded connections after long periods at elevated temperatures.
  • It is environmentally and health friendly – no hazard labeling or precautionary statements.
  • Contains no intentional chromium-based ingredients
  • Significantly reduces the formation of hexavalent chromium when used at 300°C+ on high chromium alloys.
  • Contains no calcium or magnesium ingredients.

 

 

Benefits and performance

 

  • Significantly reduces hexavalent chromium formation when used at 300°C+ on chromium containing alloys
  • Wide service temperature range: -30°C to 900°C
  • Excellent heat resistance: Fully functional anti-seize property up to 900°C; higher temperatures have not been tested.
  • Provides a controlled coefficient of friction during assembly, promoting accurate tensioning.

  • Very good load capacity: 4 ball test of ~3000 N

 

Reliable and safe operation of gas and steam turbines and turbochargers

Sustainability features

 

  • Provides decades of durable performance, allowing maintenance after long periods at elevated temperatures to minimize material usage and waste.
  • Offers a very favorable EHS profile (no hazard symbols) while providing high performance under stress.
  • Prevents the formation of hazardous substances (Hexavalent Chromium Cr(VI) ), even in high temperature applications.

Technical information

Screw testing

MOLYKOTE® P-3700 anti-seize paste provides consistent, repeatable forces over multiple tightenings (5), regardless of screw type.

 

The new MOLYKOTE® P-3700 anti-seize paste successfully suppresses the formation of yellowish hexavalent chromium at high temperatures while providing a fully functional anti-seize property.

P-3700 was designed primarily for gas/steam turbine applications. Here, temperatures above 900°C are very unlikely, if at all. Higher temperatures have not been tested.
