Teflon coating or alternative
Teflon coating or alternative
(OP)
LS,
We are applying a teflon coating (PTFE / FEP) to a stainless steel surface for its non-stick properties. Problem is that in some occasions the coating lets loose.
- Is there a method to test the bonding of the teflon coating to the stainless steel?
- Is there an alternative for teflon as a non-stick coating, that can be used up to approx. 250 C
- What method can be used to test non-stick properties of a coating (fluids will be eg. crude oils etc).
thanks,
DYV

Is the stainless properly cleaned before the ptfe coating is applied?

I have used phenolic coatings and Ryton coatings and parts with very good success in some very aggressive environments.

In our cleaning procedure for parts to be coated and/or cured we run them through a Pyrolysis Oven prior to grit blasting or any additional surface modification. We are getting rid of the organics first so we don't cover any organics up have have problems later, both during and after curing.

tungsten disulphid may be an alternative. it can take the head better than the teflon and does not require a bonding agent. also an inert material so your safe with the oil. just make sure to use a company with a good rep so its applied properly.
