EVERLUBE® COATINGS
EVERLUBE® COATINGS
Everlube® coatings are a range of tough coatings known as dry film lubricants that provide low frictional resistance between two mating parts.
Dry film lubricant coatings exhibit distinct properties that depend on their structure and composition. These properties include high load-bearing capacity, very low coefficient of friction, high temperature resistance, and increased resistance to chemical attack, abrasion, and corrosion.
The Everlube® coatings range includes environmentally friendly and REACH compliant coatings as well as air cured, high temperature and PTFE.
In addition to the Everlube® coatings range other leading product brands include Lube-Lok®, Lubri-Bond®, Ecoalube®, Ever-Slik®, Esnalube™, Perma-Slik®, Electrobond®, Formkote® and Henco-Mask™.
When dry film lubricants like Everlube® coatings are used
Dry film lubricants are often used when other lubricants, such as grease and oil, cannot be used due to temperature, load, wear, migration, and debris, which can cause the liquid to change its fluid state and no longer provide protection. Under these conditions, a dry film lubricant will remain intact, providing continuous lubrication.
How Dry Film Lubricants Work
There are two main categories of dry film lubricants, which are crystalline lattice (lamella) type structures, such as Molybdenum Disulfide, Tungsten Disulfide, Graphite, and Fluorocarbons such as PTFE.
For crystalline type structures such as Molybdenum Disulfide (MoS2), the shear forces between the layers are weak, resulting in lubricity between the sliding surfaces.
The key factors for PTFE coatings are firstly its ability to resist attack from other chemical structures, secondly its bond strength, and thirdly its ability to repel other atoms, which in combination gives PTFE coatings their ultra-low coefficient of friction and excellent chemical resistance.
Typical Applications of Everlube® Coatings
- Fasteners, springs, bearings, cams, gears, and seals
- Aerospace hydraulic fittings, valve components, and non-intrusive medical instruments
- Shafts, splines, and bushes
- Rubber and other non-metallic substrates
- Saw blades and secateurs
- Automotive fasteners, seat slides, and rails
- Petrochemical, oil, and gas subsea and topside components
