Low Friction Coatings

Friction and surface release solutions for applications where liquid lubricants cannot be used.
Thermal Spray Coatings

Zinc, Bronze, Brass, Silver, Stainless Steel, Aluminium and Copper coatings for a wide range of applications.
- Zinc Thermal Spray Coatings
  
  With impressive corrosion resistance properties, zinc is commonly chosen as a protective coating on a number of components that have to withstand harsh environments.
- Bronze Thermal Spray Coatings
  
  Of all our thermal spray coatings, bronze is often chosen for its visual and architectural appeal.
- Brass Thermal Spray Coatings
  
  Similar to our bronze thermal spray coatings, our brass thermal spray coatings are another coating option that is popular for components that require a visual appeal.
- Silver Thermal Spray Coatings
  
  Silver is often chosen due to its superior levels of conductivity compared to other materials such as steel and even copper.
- Stainless Steel Thermal Spray Coatings
  
  Stainless steel thermal spray coatings provide an enhanced abrasion resistance, producing a hard surface to be used under a PTFE coatings.
- Aluminium Thermal Spray Coatings
  
  Our aluminium thermal spray coatings offer excellent corrosive resistance on a metal surface.

  Copper thermal spray coatings are an excellent conductor of electricity, often applied to components used in the electronics industry
Surface Preparation

Surface preparation is the essential first stage treatment when it comes to applying any type of coating.
- Bead Blasting
  
  Bead blasting is often used in creating a uniform surface finish on machined parts.
  - Dry Bead Blasting
    
    Dry bead blasting is primarily used on stainless steel finishing, for any type of fabrication and gives the metal a satin finish.
  - Wet Bead Blasting
    
    Wet blasting, sometimes referred to as vapor blasting is the process for removing a coating layer (e.g. paint, rust, dirt) from a surface.
- Industrial Paint & Powder Stripping
  
  Expert paint and powder removal treatment to extend product lifespan.
- Grit Blasting
  
  By creating a smooth surface, grit blasting removes the pits and cracks that frequently harbour moisture and contaminants.
  - Aluminium Oxide Grit Blasting
    
    Due to its high etch properties, its ability to be recycled and its fast working speed, aluminium oxide is an extremely popular media that we offer in our grit blasting service.
  - Dry Ice Blasting
    
    Dry ice blasting is an environmentally friendly coating removal solution which uses a solid form of carbon dioxide to strip unwanted paint, rust and other coating layers without damaging the surface material underneath.
  - Glass Grit Blasting
    
    Glass grit blasting is a low cost and low impact media, often used for vehicle and automotive part refurbishment.
  - Plastic Grit Blasting
    
    Plastic grit blasting is a plastic media (often melamine) that can be used for cleaning, coating stripping and deflashing purposes.

Product Design Service

We know that not all coatings applications have a one size fits all solution.
PEEK Coatings

VICTREX PEEK coatings are typically used to improve resistance to chemicals, corrosion, abrasion and wear when applied to metal substrates.
PTFE Coatings

PTFE (PolyTetraFluoroEthylene) coatings, often referred to as Teflon® or Xylan® coatings offer a tough, heat-resistant finish with almost complete chemical inertness.
Teflon Coatings

The versatility of Teflon coatings allows for almost unlimited application to a wide variety of part sizes and configurations, always adding value far beyond the inherent non-stick qualities.
Xylan Coatings

Whitford Xylan coatings are dry film lubricants and can be combined with high-temperature organic polymers resulting in “plastic alloys” formulated to provide unique and desirable properties.
Halar® Coatings

ECTFE coatings (Ethylene-ChloroTriFluoroEthylene) are better known by the brand term Halar® ECTFE coatings. Halar® ECTFE is resistant to most bases, acids and organic solvents and is widely used in both the chemical processing and pharmaceutical industries. Anti-static and filled versions are available...

ETFE (also known as Tefzel™) is a thermoplastic polymer that when used as a coating offers similar properties to PTFE and other fluoropolymer coatings. ETFE is highly resistive to chemicals and acids and offers extraordinary advantages, such as increased mechanical strength, abrasion...

Bronze Filled PTFE
Better dimensional stability and lowers creep, cold flow and wear

The addition of Bronze to PTFE gives better dimensional stability and lowers creep, cold flow and wear. It increases hardness and compressive strength whilst also increasing thermal and electrical conductivity.
