Fluoropolymer coatings are used in a number of key applications. For example, where low friction or non-stick is required. If corrosion resistance is the objective, then Halar (ECTFE) or PFA are often used. Conductive coating versions are also available. Fluoropolymer Coatings >>
The TempCoat® range is the family name given to the fluoropolymer coatings applied by Impreglon UK. The TempCoat® method creates a high quality polymer surface. These coatings have excellent sliding, non-stick, release and dry lubrication properties and the TempCoat® process ensures that the coating is securely anchored to the base material (substrate).
MagnaCoat® surfaces are heavy-duty fluoropolymer coatings which are pinhole free. They can also offer good non-stick properties and some have high electrical and impact resistance, even at elevated temperatures. The coatings provide excellent barrier protection to resist aggressive chemicals and other sources of corrosion. The MagnaCoat® range of coatings are probably the best corrosion resistant coatings available. MagnaCoat >>
Low Friction Coatings
Where low friction coatings are needed, PTFE coatings are usually used. Hard wearing low friction coatings can be achieved when combining fluoropolymer coatings with plasma reinforcement (such as stainless steel, Tungsten Carbide or ceramics). Low Friction Coatings >>
Special coatings that offer galvanic protection can be used to create a barrier layer. These coatings corrode in preference to the substrate when the coating is damaged. In addition we have corrosion resistant coatings where corrosion is prevented from happening due to the non-porous nature of the protective coating.
These coatings, such as Halar, have thicknesses that range from around 200 microns to over 800 microns. Some of these coatings will withstand very aggressive and abrasive environments. Impreglon chemical resistant coatings can be found throughout the chemicals and petrochemicals industries and applied to parts ranging from valves to vessels. Chemical Resistant Coatings >>
Non Stick Coatings
Special polymers (fluoropolymers, such as PTFE) reduce the surface energy of the substrate surface and prevents many different substances from sticking. The choice of non-stick coating from the hundreds available to Impreglon UK is made based on experience and knowledge on how different fluoropolymers behave in different applications. Non Stick Coatings >>
The PlasmaCoat® method combines the outstanding hardness and wear resistance of thermally sprayed metal and ceramic coatings with the non-stick and sliding properties of polymers (both fluoropolymers and other polymers). Plasma coatings can be used in their own right to give hard wearing surfaces. Plasma Coating >>
Polyurethane coatings come under the TempCoat® umbrella and are used to give impact resistance and sound deadening. Usually applied at thicknesses from 1mm upwards, the polyurethane coating system is available in a range of colours. Polyurethane Coatings >>
Halar® ECTFE, a copolymer of ethylene and chlorotrifluoroethylene, is a semi-crystalline melt processable partially fluorinated polymer.
Choosing the best coating system for a particular application comes from many years of experience and a comprehensive knowledge of our industry. We won’t simply offer you the cheapest coating or the one that suits us – we’ll offer you what we believe is the best for the job. So don’t be surprised if we ask you lots of questions as we need to fully understand your problem and requirements. As a key industrial coating solutions company, we take pride in our workmanship.
We have a close working relationship with Whitford, who manufacture fluoropolymer coatings under the Xylan® brand, and with Chemours, who manufacture the Teflon® range of coatings. This ensures we are kept abreast of the latest developments in coating technology.
It is a common misconception that Xylan® or Teflon® is an individual, specific coating. In fact they are brand names which cover a huge range of fluoropolymer coating systems. A fluoropolymer has a Fluorine atom in it – hence the F in PTFE for example. The system may be a single layer, two layer or three or more layers. The coatings themselves are based on different resins, such as PAI (polyamide-imide), PPS (polyphenylene sulphide), epoxy and polyurethane.
In addition to resins and fluoropolymers, the coating systems have additives, pigments and fillers to achieve specific properties: corrosion protection: abrasion resistance: electrical conductivity / resistance; lubricity; aesthetics; non-stick; thickness; colour. The ratios of these various ingredients are varied to achieve different results. All of this is carried out by the coating manufacturers.
But you need not be concerned about choosing the best coating system – that’s our job!
The coatings are applied by us here at our purpose built facility in Tamworth. In some cases we may utilise the coating facilities of our sister companies - for example, if you require very high volumes of fasteners to be coated, we would liaise with one of our European facilities who specialise in this field.
