PTFE in PTFE coatings 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.
Our robust and partially patented premium polymer surface 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:
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 5 x 2,5 x 2,5 meters.
MagnaCoat® coatings are thick-film polymer and fluoropolymer coatings with a virtually pore-free surface. MagnaCoat® is suitable for heavy-duty corrosion protection. This 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.
Typical applications in the chemical industry include:
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.
TempCoat® polymer 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 chemical industries.
