Polymer coatings

Polymer coatings

What type of surface coating is suitable for my application? It is not always easy to find a straightforward answer to this question, especially when it comes to the wide range of possible polymer coating processes. However, the number of possible coating options can be narrowed down quite well by our experienced experts. Before we make a final decision, we often test different solutions by means of sample coating processes.

Which coating is suitable for which application?

Which coating is suitable for which application?

Sometimes, the first approach does not give a clear answer, especially when it comes to the wide range of possible polymer coating processes. Although our experienced experts are quite good at narrowing down the number of possible coating options, sample coating processes with several coating varieties are often inevitable.

PTFE coatings as everyday polymer coatings

PTFE stands for polytetrafluorethylene, a semi-crystalline polymer consisting of fluorine and carbon. When heated, the consistency of PTFE becomes soft and rubbery, but usually not meltable or liquid. PTFE has anti-adhesive properties and can hardly be wetted. It can be subjected to a wide range of temperatures (continuous service temperatures: from approx. -200°C to 250°C; temporary exposure: up to 300°C; crystallite melting point: 327 °C); PTFE is almost incombustible. All of these properties make PTFE polymer coatings ideal for the coating of frying pans, for example PTFE coating processes are part of our everyday business.

Excellent protective coatings for almost all base materials

Our robust and partially patented premium polymer coatings are applied onto the workpieces using special coating methods. Our special technique ensures long-lasting coatings which become extremely well anchored in a wide variety of base materials:

Protective coatings for almost all base materials
  • Steel
  • Stainless steel
  • Ceramics
  • Plastics
  • Copper
  • Aluminum

The fields of application are varied: Our customers from the chemicals industry order this type of protective coating for containers, pipelines, valves or sensitive probes. Anti-friction and non-stick coatings prevent the formation of deposits, an indispensable feature in this area.

In electrical engineering applications, the coating thickness determines the degree of insulation of battery connectors or bus bars. When it comes to electroplating, the electrical insulation and non-stick properties have proven to be ideal for bathroom radiators, racks and wash baskets. Surface coatings on medical instruments, such as tweezers, grips for pliers or electrode spoons, have insulating and dirt-repellent effects and are able to withstand sterilization temperatures.

Polymer coatings have many convincing advantages

Non-stick properties

Even extremely adhesive materials will not adhere to polymer coatings. The result: significantly reduced cleaning efforts and a lower consumption of cleaning and release agents. Thus, it is possible to effectively shorten and reduce machine downtimes caused by maintenance work or soiling. Since PTFE or PFA coatings enhance the surface quality of your components, this effect will be further intensified.

Anti-friction properties

With a roughness of partially below 1.0 µm and a virtually pore-free surface, our high-performance polymer coatings get their job done with minimum sliding friction. Our experienced specialists will define the values for your individual application. To ensure excellent protection against wear, we apply additional reinforcement layers.

Corrosion protection


Fluoropolymer coatings offer first-class protection against atmospheric corrosion, contact corrosion and condensation corrosion. Depending on the specific coating material and individual conditions, the thickness of the protective coatings may vary between 5 and 1500 µm.

Resistance to high temperatures and chemicals

Resistance to high temperatures and chemicals: Viscoelastic polymers are characterized by excellent resistance to halogens and solvents as well as by high resistance to acids/alkalis (up to pH 12). They do not have any difficulty whatsoever in withstanding temperatures between -40°C and +290°C.

PTFE coatings: No adhesions during work with rubber or food

No Adhesions during Work with Food

Teflon® coatings stand out with their excellent non-stick properties: Even tricky ingredients, such as adhesive, rubber or sticky food, will not adhere to the hydrophobic surface finish. Teflon® was originally developed for cookware. Today, we use the 5 to 50 µm thick synthetic surface coating in single-, double- and three-layer systems, which allows us to cover a broad range of possibilities. PTFE coatings can be applied to workpieces in dimensions of up to 10 x 3 x 3 meters.

MagnaCoat®

MagnaCoat® coatings are thick-film polymer and fluoropolymer coatings with a virtually pore-free surface.

This is how MagnaCoat® works

MagnaCoat® can be applied electrostatically and is thermally melted. Depending on the heat capacity of the parts to be coated, the coating thickness is between 0.3 and 0.5 mm. The coating's mechanical strength allows for subsequent machining (e.g. grinding). Thus, it is also possible to adhere to the required dimensional tolerances.

Properties of MagnaCoat®

MagnaCoat® is a high-quality, thermoplastic fluoropolymer characterized by good thermal, chemical and dielectric properties. MagnaCoat® coatings offer outstanding corrosion protection, good non-stick properties and high dielectric strength, even at higher temperatures. Besides, they offer excellent barrier properties in terms of chemical resistance. The MagnaCoat® process creates virtually pore-free, non-diffusing thick-film coatings. The combination of these brilliant properties makes MagnaCoat® the ideal solution for applications subject to chemically aggressive conditions.

Base materials which can be coated with MagnaCoat®

All materials made of aluminum, steel, stainless steel or other alloys are suitable for MagnaCoat® plastic coating.

Fields of application of MagnaCoat®

MagnaCoat® is suitable for heavy-duty corrosion protection. The polymer coating has been developed for applications which require not only chemical resistance but also non-stick properties. Besides, this type of coating can be used where the diffusion resistance of comparable coatings is not sufficient. The temperature resistance exceeds the values of the systems which are usually used in this area.

Typical applications in the chemicals industry include:

  • Storage containers 
  • Reaction vessels
  • Valves
  • Agitators
  • Sensors
  • Rotary dryers or calender rolls

TempCoat®

TempCoat® coatings are created in special polymer and fluoropolymer coating procedures.

This is how TempCoat® works

During the TempCoat® process, special polymer and fluoropolymer coatings are created. Due to the targeted modification of the surface structure with defined roughness profiles, the contact surface is reduced, which results in enhanced non-stick properties. Thanks to their low static and kinetic coefficients of friction, fluorinated polymer films are an indispensable coating material for a wide range of industrial applications. The slight difference between both values reduces slip-stick phenomena, which is a huge advantage when it comes to alternate movements.

Properties of TempCoat®

TempCoat® is a fluoropolymer coating characterized by high chemical resistance and excellent non-stick and gliding properties. Multi-layer reinforcement coatings or the use of special additives, such as graphite or molybdenum disulphide, make it possible to tailor the coatings to your individual application. Thus, it is possible to improve demolding processes by multi-layer, wear-resistant non-stick systems or to use the coating's outstanding dry lubrication properties to protect sliding applications against malfunction.

Base materials which can be coated with TempCoat®

TempCoat® coatings are applied to aluminum, steel, stainless steel, copper, ceramics and plastics.

Fields of application of TempCoat®

TempCoat® coatings come into play in technical areas whenever high wear resistance and good gliding and non-stick properties are required. The efficient and trouble-free processing and transportation of metals, plastics, paper and foods in different production processes are no longer possible without excellent anti-friction properties of surfaces which come into contact with products. Sliding bearings modified with TempCoat® are indispensable in many applications and sectors, such as the printing, bakery and chemicals industries.
