How to do Teflon/ non-stick coating
Disambiguation --
• If you seek a service to re-apply non-stick coatings to your cookware, please see Thread 29692
• If you're looking for repair spray; it seems no longer available, but please read & comment on Thread 10027 or Thread 12601
• This thread is for technical info on how non-stick coatings are made & applied.
Q. My employer asked me to pick up either a pot or a pan made of stainless steel, with a teflon finish, and no other kind of finish. I went to a store called The Bay (www.hbc.com/bay) which is probably the largest high end department stores in Canada, and possibly one of the best in North America. They had about 30 different brands of pots and pans and many were stainless steel, but not one of them had a "Teflon" coating. There was T-Fal and Stoneware and a couple starting with an E, but no Teflon.
Can someone tell me if Teflon is a brand name or a product that goes into other non-stick coatings. I would really like to find out.
Please either give me the answer or tell me where to look on the web.
Much appreciated...

A. Teflon is a trademark of Dupont for PTFE--polytetrafluoroethylene. It is a very slippery, very chemical resistant, very high temperature plastic, which I always believed to have been invented by Dupont.
The company which makes T-Fal also claims to be the inventor of PTFE. I would not want to slander either by saying there is no difference, but for your boss' purpose, I think the answer is "T-Fal = Teflon = non-stick".
Nonetheless, most non-stick cookware is aluminum rather than stainless steel. You may need to shop a bit to find stainless cookware with a non-stick coating.
Good luck.

A. Hi Noni,
As said Ted, Teflon* is a trademark of DuPont, and under this name they sell different polymers and copolymers like PTFE, FEP, PFA, ETFE, etc. There are in the market other trade names for PTFE coatings like Silverstone, Teflon S, Teflon 2, from Dupont; Xylan, Excalibur, Dykor, Xylar from Whitford Plastics, etc. There are some companies who sell PTFE dispersions to be applied on frying pans with different names.

Q. I have a small breadmaker mixing blade which needs re-coating with PTFE/Teflon/Fluoropolymer (operating temperature up to 275 °C). The manufacturer's price for a new blade is almost the gross national product of a third world nation. If I can re-coat this part myself, I can save buying a new blade now and more in the future. How can I re-coat and stove this blade myself? What product would you suggest I use and is there a distributor in the UK?

A. John,
First off, please have a look-see at your yellow pages and find out who does PTFE coating ... there must be oodles of Companies who do this in the UK ... try also the Plastics Institute (or an equivalent) who can tell you whom to go to. Try also some of the listed 'suppliers' in plastics who might tell you (politely, one hopes) where to go to.
Horsham is a small town (used to be the UK's biggest village of 16,000 or so back in the 40's) so you may have to go to the library for London's Yellow Pages.
If your dough wasn't so 'tough' to mix and if the temperature were lower, I'd think of using straight unreinforced teflon but that's only good for 400 degr. F., I believe, and PTFE is not known for its strength and stiffness. There is a glass reinforced teflon which is stronger but think that the food inspector will not take too kindly to your using that material!
The UK does have its own 'teflon', PMCTFE but I'm not familiar with its properties.
I doubt that you could recoat the blade yourself and suggest you go to a specialist Company ... and if these blades only last a short time, why not get another one made up in metal and get that coated, too?
Cheers ... and happy mixing !

Q. I am interested in gaining expertise in coating of all sorts on aluminum cooking utensils. Is there anybody who could guide me or provide any sort of assistance or information as to who should I contact.
Most of the kitchen utensils are made of stainless steel, or iron or sometimes even aluminum. I want to know if there is a supplier who can supply me a Teflon coating machine, which can do a Teflon coating on utensils of various sizes (usually pan size). Can a single machine be used to coat different metals like mentioned above. Maybe in a batch or a first in first out basis, or one at a time basis.

Q. I am doing an experiment to spin plastic waste into suitable non-woven scouring pad. My initial idea borrows from the method whereby granular sugar is spun into cotton candy. If the granular sugar is replaced by granular plastic beads then you will get the plastic cotton candy instead of the sugar cotton candy. If the condition is correct i.e., heating temperature, rpm, size of holes of the spin head, then the fine plastic threads that collect at the surrounding wall will build up to form a sheet of non woven plastic pad. The sheet of plastic pad is then slowly taken off the wall by moving it up along the wall. At the right height the sheet is slit and carried unto a revolving wheel before coiled into bundles and later cut into squares of the appropriate size. The problems envisaged are:
1. The spin head that spun the plastic granules into plastic threads is heated by an OPEN electric coil to melt the plastic. This requires complete electrical insulation.
2. The plastic threads will stick to the walls, preventing it to be moved up easily.
My question is: Is there anything in the market like "spray-on" teflon coating for electrical insulation (the spin head) and for "non-stick" teflon coating for the wall?
In the long run, in case my idea works I will certainly benefit using the practical teflon coating rather than using the usual ceramic coating.

Q. I want to be able to recoat damaged photocopier rollers, frying pans and other simple household or non-complicated articles at a very low cost and doing it at a small scale. Can anyone help?
Atemnkeng, Denis- Yaounde, Cameroon

A. It is not so easy to apply the teflon coatings. The process will be:
- degrease the pieces to be recoated
- take out the old coating by grit blasting
- apply the primer (liquid) by spray gun
- dry the primer 200 °F 5 minutes
- apply the second and 3th coat wet on wet
- cure the coating at 750 °F
As you can see you'll need some special equipment to do it. Good luck

Q. Is there a Teflon spray coating available that can be applied to low profile die cutting plates. coating purpose is to resist adhesive build-ups and have a reasonable life.
Jim Taber- Orangeville, Ontario, Canada
2002
A. Try Miller-Stevenson (also known as MS), they have a variety of chemicals, mold releases, etc in spray cans. Another possibility is to use wax. The stuff sold in automotive supply stores to ease putting tires on rims can be poured into a spray bottle and makes a decent lubricant.

Teflon application in the home
Q. I want to apply Teflon to the interior of a home rotisserie. Is there a spray-on or paint-on product that I can use without industrial equipment?
Bill Burke- Chula Vista, California
2002
A. To make a Teflon coating you must "cure" the coating at 375 °C. Normally at home we don't have the oven to obtain this temperature. You can find in the market paint that contains PTFE that can help you having a easy cleaning surface, but this paint do not last as long as a Teflon coating.
Jordi Pujol- Barcelona, Spain
2002
? This response indicated that PTFE needs to be cured at 375 °C. It also indicates that home ovens cannot go that high. Self cleaning ovens will go higher to 482 °C.
Would this temperature destroy the PTFE coating and render it useless? The time at temperature can be controlled by unplugging the stove.
Your thoughts please.

A. Hi, Tim. You can name any material and there will be people who think it's dangerous to use, but I personally think it's safe to use Teflon coated cookware. That does not mean it's safe to cure Teflon at home. Do a search for 'parrot Teflon' and read about how the fumes from overheating Teflon is known to kill parrots. I think it is exceptionally risky to try to cure Teflon with the self-cleaning cycle of a home oven ... or to do any industrial process in your cooking oven.
You probably cannot get the Teflon to adhere properly anyway. There is more to it than curing, the base aluminum requires the application of a special porous metallic coating to provide "key" so the Teflon will flow into the nooks and crannies so the Teflon will adhere.

Starting a Teflon Recoating business for Pots & Pans
RFQ: I have been looking at starting a business in South Africa on recoating kitchen utensils with Teflon or similar. I need information on suppliers of relevant plant to do the job. Is anybody doing this in South Africa? Any information on this subject will be appreciated.

Q. Hi and thank you for taking time to read this message. I just graduated from a local university and I majored in metallurgic engineering, I want to start a business of my own and thought that Teflon coating would be a good idea. I know about the basic properties and application procedures of Teflon, but I would like to know more about the different types of applications, and the necessity of primers and mid-coats. I am looking for a mentor who would introduce me to the business of Teflon coating.
Again, thanks for reading this.

Q. HOW CAN I RECOAT COOKING POTS WITH PTFE (D-I-Y).
STAN FPRIVATE - LUSAKA. ZAMBIA
2003
Q. I'm sick and tired of throwing away Teflon coated pans. No one in our area re-coats them. I'm seriously considering starting a business that would provide this service. I don't know what is involved or how to go about it. Can you help me in finding out what would be involved and the approximate cost of equipment for starting such an operation? Perhaps no one is doing it because it is too costly or too difficult to do as a small endeavor? I'd greatly appreciate any help I can get. Thanks.
S. Fernandesretired - San Jose, California

A. It simply is not cost effective to re-coat. The original mfgr. coats them in hundreds at a time, normally all the same size. To recoat, you would need to strip the old coating, polish the pan and recoat. Typical small business needs to charge at least $50. per hour. You would have at least an hour per pan. Then add shipping on top of that. You simply cannot compete, especially with all of the cheap stuff coming from China now.

A. I respectfully disagree with James Watts. There are a couple of Teflon recoaters: Ed. note: Update Dec. 2013 -- The domain frypanman.com has been just a link farm for many many years now, and fluorosurfacing.com has not existed for years either. But readers seeking a re-coating service, please see Thread 29692, "Teflon re-coating service for pots, pans, waffle irons" |
They charge between 10 and 20 dollars a pan, depending on size and volume.
I gather that they do a bunch of pans at a time to get some of the benefit of larger production runs. Few people would pay even that to re-coat a pan that costs only $10 to begin with, but some higher end cookware lines like LTD have 10" nonstick pans that cost $70.
I have never applied a Teflon coating but having researched it a little, believe the process is something like:
-Sandblast the old finish off the pans
-Mix a batch of the coating
-Apply the coating
-Cure the pans in an oven
You would need a sandblaster (the fine 'beadblasting' type), a spray booth, and some kind of oven. The best starting point would be to talk to the Teflon people at DuPont and find out more about the process. Remember that what I describe above is based on slightly informed speculation rather than my own experience.
If you do go into the re-coating business, I've got some pans that need it. Good luck.
Bruce Poropat- Berkeley, California

A. I'm sure it will be a great business. I'm Teflon coating in Spain, and I believe you are in the good way.
To reduce pollution it is good to recycle. You can learn more about the process at www.fisasa.com/teflon_proceso.htm
Ed. note: Update Dec. 2013 -- The domain 'www.fisasa.com' is still good, but the '/teflon_proceso.htm' page no longer exists.
If you need any help, I'll do my best.

Teflon for DJs?

A. Tell us what a "slip mat" is made of and what is it used for and we can give you some alternatives. Setting up your own Teflon spray rig and oven is not a wonderful idea.
James Watts- Navarre, Florida
2004
A. Do a google search under "fluoropolymer spray coatings" and you'll find many manufacturers as well as contract coating houses. Teflon is itself a brand name for a series of DuPont coatings. There are many types of Teflon and hundreds if not thousands of other fluoropolymer coatings.

Q. The "slip mats" are made of various fabrics most are made of nylon dycron and other "y" "on" fabrics. I looked on the DuPont site for such products and found a spray for stain protection like a Teflon scotch guard. Do you think this would work. Thanks to all who did {or will} respond. Thud Rumble thanks you.
P.S. I have ABSOLUTELY no plans in using any bake on products. The mats are made of fabric.
Alex KarabinMusic - Aurora, Ont., Canada
2004
A. Okay, I still do not know the use of a slip mat, or size or properties you are looking for. The stain guard very probably will not work. There are Teflon mold releases sold in spray cans that might work, but their longevity might be questionable. Have you considered a UHMW tape? It comes in many widths, some varied thickness's and some with different choices of adhesive used. This is slightly harder than teflon and is very nearly as slippery. It can be bought in thicker sheets, but it might be hard to glue. Normal color of the tape is a nearly pure white. Does not yellow much with age either.

Let me guess: a slip mat is a disc a DJ puts on the turntable underneath the vinyl record so he can more easily make that annoying screech that comes from twisting the record backwards? :-)

A. The problem to "recoat" the Teflon* is that you will need one oven able to rise 400 °C (750 °F)to polimerize the coating. It will be cheaper to find a Teflon Coater to do that job.
;-)
- Barcelona, SPAIN
July 20, 2009
A. I have to agree,
Teflon is not a D-I-Y application, I would contact the manufacturer and find out the price of a replacement part and call around to find the price to get the cutter re-coated with teflon.
Go with the cheaper option.

Hi Peter Coetzee of Cape Town South Africa -- did you have any luck finding out about Teflon coating?
Johan van der MerweBakery - cape Town South Africa

A. Hi Johan. Teflon for food service cannot be applied by painting. Although there are some teflon lubricants (oils and greases which also contain tiny teflon particles), you can't use these for food because a portion will come off in the food. The application of teflon anti-stick coatings to food service items is a far more complicated process than painting.

Q. I am a maintenance person that repairs glue pot assemblies. I normally send out our glue pots when the surface becomes so worn and scratched that the Teflon coating is gone. This is both time consuming and extremely costly. I can do the repairs myself but I was wondering if there was a spray or a dip-in Teflon coating product that I can buy for this purpose? The glue pots can get up to 300°
