Wear-reducing piston anti-friction coatings

Piston Anti-Friction Coatings

Improve fuel economy and reduce
piston-and-ring wear and noise

To achieve improved fuel efficiency and engine
performance, choose Molykote anti-friction coatings
(AFCs) from Dow Corning for lubricating pistons and rings.

Molykote anti-friction coatings bond strongly with all
metal surfaces to provide long-term lubricity, lower the
coefficient of friction and improve engine performance to
reduce carbon output.

Combined with a specialized application process, these coatings:

  • Reduce metal-to-metal friction, engine noise, scuffing and wear.
  • Provide reliable lubrication without degradation over time.
  • Help lower emissions and reduce fuel usage through more efficient combustion.

Paint-like products with submicron-sized particles of solid lubricants, Molykote anti-friction coatings are:

  • Applied to pistons and rings by spraying or printing
  • Cured with heat to a dry-film lubricant, strongly bonded with the metal
  • Available in a range of choices for specific operating conditions and engine designs, aluminum-to-aluminum and aluminum-to-cast iron
