Fluoropolymer coatings offer superb protection against the harshest of substances and very few can affect the strong carbon-fluorine bonds that give these coatings such unique properties. Some typical applications are:
Where harsh substances are processed, it is quite common for designers to specify extremely expensive alloys such as Hastelloy or Inconel.
In many cases it is perfectly acceptable to use 316 stainless steel, carbon steel or similar and with the addition of either a PTFE, PFA or FEP coating, the service life of the part will be substantially increased at a fraction of the cost. We have a range of options available including high-build topcoats and filled mid-coats which act as a physical barrier by increasing the diffusion path of the corrosive process.
We also have numerous formulations that are blends of resin and fluoropolymer that can provide additional mechanical strength and abrasion resistance. Depending on the process, we can select coatings that are extremely durable in acidic or alkaline environments. Other resin systems are available where solvent attack is likely.
Modern chemical processes are highly complex and mostly involve a range of substances at different concentrations. Temperature and pressure are also key factors to consider when selecting a suitable coating system.
We have huge resources of information relating to the effect of almost all substances on fluoropolymer coatings and other plastic materials. With this knowledge, we are able to select the correct type of coating that is most suitable for your application.
