Coating technology helps our customers to achieve genuine product and process advantages.

Our aim is simple: to provide individual solutions that optimise both our customers’ products and processes.

Over the last ten years we have developed a number of high- performance surface coatings that have given our customers genuine product and process advantages.

Advanced technology is employed to deliver high performance, and helps increase productivity in the assembly and application of o-rings, reducing the required level of customer applied lubrication. Essentially any surface treatment is designed to reduce friction and enhance performance.

These surface treatments are suitable for adhesion to elastomer compounds such as EPDM Ethylene Propylene, NBR Nitrile and FKM Fluorocarbon.

Common benefits of Superior Seals applied coatings:

• Reduce surface friction • Solvent free
• Reduce insertion force • No effect on substrate ageing
• Provide wear resistance • No effect on chemical resistance
• Prevent surface adhesion • Drinking water approvals available
• Silicone free
• Stable in storage

Our high performance compounds combined with a surface coating not only guarantee a safe and robust assembly; but also an increase in productivity output; that could be an increased flow in feeding systems, preventing blocking or reduction in assembly forces.

Customised coating solutions – your advantage

Our environmentally friendly PTFE coatings offer clear advantages over traditional lubrication methods such as oils, greases and powders, which can contaminate products or equipment; in addition you can avoid assembly damage and gain improved abrasion resistance.

With an increased level of camera technology to check components in assembly, it means you must be able to differentiate between various components. Our coloured coating provides an easy solution for systems or operators to check if a component is present giving our customers full security. We also have the potential to develop other colours for applications with specific requirements.

There are many variables within the coating process that must be understood and controlled to achieve a consistent and repeatable coating every time.
