Dry Film Lubricants

Applying a Lubrication Coating Over Sliding Surfaces of Parts Reduces Friction and Wear

  • Dry film lubricants formulated with solid lubricants, such as molybdenum disulfide(MoS2), PTFE and graphite, and binders. Applied like a coating, they form a lubricating film at room temperature or after being dried by heating.
  • Applicable to diverse parts, such as metals, plastics, and rubbers.
  • deal for applications aimed at improving initial running-in, wear resistance, adherence prevention and low friction performance, those involving locations where oil and other normal lubricants cannot be used, and those based on a desire to achieve a synergy effect with such lubricants.

To prevent wear of metal components.

To reduce the amount of oil and grease used for small components.

For oilless sliding parts.

To improve wear resistance or prevent adhesion of the rubber components.

Seizure Prevention

  • Contain solid lubricants such as molybdenum disulfide, known for superior lubricity under heavy loads, in high concentrations.
  • As the film is relatively soft, the coats are excellent in preventing seizure, while quickly providing an ideal lubricating surface during initial running-in lubrication.
Product Name Treatable Material Appearance Binder Curing Conditions Solid Lubricant Additives Remarks
Molydry 1610 Metal Black Epoxy Resin 180℃×30min Molybdenum Disulfide,Graphite Excellent initial running-in and anti-seizure performance.
Molydry 1670 Molybdenum Disulfide Excellent anti-rust and chemical resistance performance and amenability to dipping and tumbling treatment.
Molydry 5511 Inorganic Compound 150℃×30min
（Drying under room temperature permitted） 		Molybdenum Disulfide,Graphite Excellent heat resistance and load bearing performance and amenability to dipping and tumbling treatment.

Low Friction

  • Contain PTFE, known for superior low friction performance.
  • As the film is relatively hard, the coats are ideal for the pursuit of even more enhanced low friction performance and provision of permanent lubrication under low surface pressure.

Heat and Wear Resistance

  • Contain solid lubricants, such as molybdenum disulfide, known for superior lubricity under heavy loads, and graphite, known for superior heat resistance, in high concentrations.
  • As the film is relatively hard, the coats have excellent heat resistance and　wear resistance, and are therefore ideal for applications with demanding temperature and load conditions.
