What is the LRC Process?

The ULTRA LRC process is a unique method of fusion-bonding a dry, solid lubricant to metal surfaces. This treatment prevents metal-to-metal contact and provides exceptional resistance to wear, galling, and seizure under extremes of hear, load and atmosphere.

The ULTRA LRC Surface consists of fine tungsten disulfide particles in crystalline form, making thickness control inherent in the process. Nominal thickness of the LRC ranges from 5 to 10 millionths of an inch.

ULTRA LRC is permanently bonded to the substrate.

The LRC process molecularly bonds a solid lubricant to the surface substrate without carrier or adhesive. ULTRA LRC surfaces have been subjected to abrasion and damage from impact, overload and bending with no sign of ruptures, cracks or “flakeoff” of the lubricant.

Since ULTRA LRC is applied at room temperature, the process has no degrading effect on heat-treated parts and does not induce or remove stresses.

ULTRA LRC is virtually inert and is insoluble in most atmospheres. It remains impervious to many solvents, including chlorinated solvents and some fuming acids. It is attacked by free flourine gas and hot sulfuric and hydroflouric acids. ULTRA LRC is non-toxic, non-corrosive, and can be used on all chemically stable metals. The LRC surface is resistant to corrosion of substrate materials.

ULTRA LRC is compatible with all common lubricants, including: petro-chemical oils and greases, synthetic diester oils, stearate greases and silicones, as well as hydraulic fluids.

A Unique Solution to Friction and Release Problems


  • Enhances lubricity and release characteristics of the substrate;
  • Retains close tolerances and functional properties of substrate;
  • Becomes part of the molecular structure of the substrate;
  • Will not remove or induce surface stresses;
  • Does not require high-temperature curing;
  • Is applied without resins, binders or carriers;
  • Is inert and non-toxic.
