Perfluoroaromatic compounds can be manufactured via the Fowler process, like fluoroalkanes, but the conditions must be adjusted to prevent full fluorination. They can also be made heating the corresponding perchloroaromatic compound with potassium fluorine at high temperature (typically 500 °C), during which the chlorine atoms are replaced by fluorine atoms. A third route is defluorination of the fluoroalkane; for example, octafluorotoluene can be made from perfluoromethylcyclohexane by heating to 500 °C with a nickel or iron catalyst. [30]

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.

A dermatologist diagnoses perioral dermatitis by examination. No other tests are usually done. The first step in treating perioral dermatitis is to discontinue all topical steroid creams , even non-prescription hydrocortisone. Once the steroid cream is discontinued, the rash appears and feels worse for days to weeks before it starts to improve. Heavy face creams should also be stopped. One must resist the temptation to apply any of these creams to the face when this happens. Think of the face as a cream junkie that needs a "fix"- one needs to go "cold-turkey".
