Bonded coatings & dry lubrication

What are dry lubricants?

Dry lubricants (also known as dry film or solid lubricants) protect equipment components permanently against wear and exposure without needing to be maintained or reapplied like liquid lubricants. They are also impervious to dirt, moisture, and other environmental factors that can degrade machinery. They reduce damage from friction (two surfaces rubbing against each other, common with moving parts coming into contact) and shear (conflicting forces acting to cause pressure, which can happen with sliding shafts and threads).

A range of dry lubricants to suit specific applications can be used in bonded coatings, including:

MoS2 (molybdenum disulfide) – also known as moly dry film lubricant. It protects against friction in high load bearing situations - up to 250,000 psi.

PTFE (Polytetrafluoroethylene) coatings create a smooth, hard surface. They’re applied in one coat that welds on to the substrate. PTFE has a very low coefficient of friction and is very resistant to temperature extremes, corrosion and chemicals. It can be made electrically conductive.

Dissolved graphite - Graphite forms layers that can be customized for different degrees of flexibility, depending on the application. It’s highly durable, anti-friction, anti-oxidizing, and fire-resistant.

What are bonded coatings?

They are non-stick coatings composed of dry/solid lubricants, a binder and a solvent that together allow the lubricants to bond solidly to metal or plastic parts in a dry, uniform layer. They have excellent adhesion due to the dry lubricant.

Bonded coatings suit industries with demanding operating conditions such as oil and gas, petrochemical, and water processing. It can be used to coat steel, stainless steel, aluminum, non-ferrous metals and sintered materials, and due to its flexibility, can also be used with elastomer and plastic parts.

• Provide complete coverage with a dry, uniform protective layer.
• Prevent damage and degradation from environmental contamination and corrosion.
• Prevent/reduce friction and noise.
• Resist very high and low temperatures.
• Maintenance-free.
• Optimises production, cutting operating costs.
