Dear sir,

We do PTFE coating on textile / chemical processing machinery parts. We have a problem coating higher thickness in PTFE.

Kindly suggest. Please be good enough for giving proper information on CERAMIC COATING ON INDUSTRIAL parts where heavy abrasion is found.

Dear friend,

Is there a company in your country that performs plasma spraying or HVOF? If so, before you put the PTFE coating, ask them to spray your component with a ceramic coating like Aluminum Oxide/Titanium Oxide and you are OK

If you have an abrasion problem you can use a polyurea coating instead ceramic coating. The polyurea has a good resistance for abrasion.
Just if you have low temperature (125 °C maximum) Raul Mata
