Welcome to Micro Surface Corporation

High-quality Dry Film Lubricants for Friction, Galling, Wetting, and Corrosion

Dry film lubricant coatings, also known as solid film lubricants, or dry lubes, are designed for extreme conditions. These lubricants offer lasting lubrication, and help reduce friction between two moving surfaces. Additionally, they help eliminate seizing, galling, as well as work well in high temperatures and vacuum. Micro Surface Corporation offers specialized engineered dry film coatings for diverse industrial applications. Our best-seller dry lubricants create strong integral bonds with metal base substrates, and do not peel or crack easily.

What are Dry Film Lubricants?

Dry film lubricants are lubricants that are offered in a powder form. These lubricants are made from solid lubricating pigments, which are blended with additives and binders. When cured, these lubricants form a solid film on the part, and helps minimize wear and tear between two mating parts.

Also, these lubricants are less prone to collect soil particulates, unlike greases. Some solid lubricants like ours are engineered to resist chemicals. This makes them ideal for harsh environments such as jet engines, where they are exposed to extreme temperatures, as well as aviation fuel.

What are the applications of dry film lubricants?

Dry film lubricants are used for a number of reasons, including the following:

  • At Extreme Temperatures: Solid film lubricants are used at extremely high or low temperatures that typical liquid lubricants cannot withstand. Most liquid lubricants are designed for normal temperature applications. Beyond these temperatures, liquid lubricants may change their state. However, solid lubricants have a low coefficient of friction, which helps them retain their structure at high or low temperatures.
  • At Extreme Contact Pressures: Dry film lubricants have a lamellar structure. When applied between two surfaces, this structure allows particles to get oriented to the parallel surface, and improves its load bearing capacity. This orientation also leads to low shear stress.
  • Sliding metal-to-metal Contact Applications: The dry lubricant is used when long-term performance is expected. Most liquid lubricants may evaporate or disappear with time. However, dry lubricants continue offering protection from galling, fretting, and corrosion, when applied between two sliding metal-to-metal applications.
  • Special Applications: Solid film lubricants are also ideal for surfaces, where typical chemical additives are not found. For example, these lubricants are used in various ceramics, and polymers.
What are the most commonly used dry film lubricants?

The following are a few important dry film lubricants used in industries to avoid friction and wear between surfaces in motion:

  • Molybdenum Disulfide (MoS2)
  • Tungsten Disulfide (WS2)
  • Polytetrafluroethylene (aka PTFE)
What are the properties of different dry film lubricants?

  • Molybdenum Disulfide has a hexagonal crystalline structure. There is no moisture between lattice plates. Thus, it is ideal for high vacuum applications. The temperature limitation of MoS2 is 752oF (400°C).
  • PTFE is a fluorocarbon, which strongly resists wetting. PTFE resists all chemicals, and is one of the most slippery materials around. The coefficient of dynamic and static friction is equal to the ice.
  • Tungsten disulfide (WS2) is extremely durable of all dry film lubricants, and can withstand heavy loads of 300,000 psi. Also, this lubricant has an extremely low coefficient of friction – 0.03. It is used as a release material for extrusion dies, plastic molds, etc.
