How to bond Teflon to Teflon?

How to Glue Teflon? Teflon: Carbon backbone, Fluorine pendants Combine the reagent with the portion of the Teflon to be glued, and the fluorine atoms react with the sodium metal to form sodium fluoride, while the naphthalene attaches to the outermost layer (s) of the Teflon. It is actually those chemically bonded naphthalene rings one glues to. Apply the SI Structural Adhesive to one TeflonЃ surface. Use continuous circle to apply the SI adhesive making sure the adhesive line is unbroken. Make sure that the SI adhesive reaches the edges. Align and press the pieces together for seconds.5/5(1).

The most common application would be that of non-stick frying pan coating. Things are improving nowadays thanks to recent adhesive developments Ч primers are now available and even structural acrylic adhesives which can be used straight on this beastly surface!

Because of its high temperature resistance and excellent resistance against harsh chemicals, PTFE is often used for extremely challenging applications. PTFE is often found in electrical components, high lubricity mechanical parts, non-stick cook wear and various things such as chemical handling equipment and tank liners.

It also crops up in blended forms to add high temperature and chemical resistance to other types of plastic and interferes with their bondability too unfortunately! These materials are becoming more difficult to get hold due to shipping hazards and many workplaces are trying vlue lower worker exposure. Using an etchant allows great freedom of choice of industrial adhesive after treatment Ч this could be important if you have other performance considerations.

Fo are limitations though Ч if you are bonding dissimilar surfaces, opt for a toughened grade such as Permabond which will allow some flexibility to cope with differential expansion and contraction. Cyanoacrylate gap fill is limited to 0. Permabond also offers TA and a range of similar products with varying cure speeds. This is a two-component mix ratio structural acrylic which can be applied, without primer, to untreated PTFE surfaces and achieve a reasonable bond strength on this non-stick nasty!

Surface preparation and PTFE adhesive selection

PTFE is commonly known by the trade name TeflonЃ or the proper name УPolytetrafluoroethylene.Ф It is a notoriously difficult material to bond as it is non-stick by nature. It is often used for applications where high temperature and/or exposure to harsh chemicals will be an issue. Polytetrafluoroethylene, orTeflon, is a non-stick plastic that is often used in cookware. There is no way to glue Teflon, but there are a couple of things that can be done to restore it. Restoring Teflon Pots and Pans If Teflon pots and pans are scratched or peeling, a non-stick surface repair spray can be used. Nov 11, †Ј Same with a small block of 1" thick Teflon (PTFE). The glue kit includes a primer in a small rub-on tube like a sharpie. Wait one minute and then apply glue as per usual and hold for 30 seconds. It smells just like the regular stuff and sticks your fingers together just as well.

I have a need to glue some Teflon to aluminum. At least, it would be a lot easier than anything else I can think of to fasten it. I was in the local Canadian Tire they sell more than tires store and spotted some new stuff on the rack.

I think to myself, "yeah sure, anything but Teflon". I bough some and just tested it. The glue kit includes a primer in a small rub-on tube like a sharpie.

Wait one minute and then apply glue as per usual and hold for 30 seconds. It smells just like the regular stuff and sticks your fingers together just as well. I gave it about ten minutes to set just to be sure. Now, I was sure this wouldn't work. I tried to pluck the block off the plate.

No go. I pushed a little harder. I pushed really hard. It probably took at least 30 or 40 lbs of side pressure or more for a bonding area of about 0. Even more interesting, it was the bond to the plate that failed, not the bond to the Teflon. This looks like it will be useful stuff.

Wonder if it would do the same or similar for Delrin?

That would come in handy frequently. It is black in color and has rubber in it. Its strength is reduced because of that but it has some shock tolerance. I use it to mount tiny first surface mirrors, beamsplitters and other related goodies.

Thanks Evan that will be one to keep in mind. Loctite makes amny niffty products,one I like in particular is the expandable pipe thread sealant,no wrenches needed. I just need one more tool,just one! Thanks for the info Evan. It was the only thing that would hold for more than one flight. Rich Carlstedt. Years ago, Norton of grinding wheel fame, made a product called Chemgrip, that was specifically made for Teflon bonding.

I am glad you found the product Evan.. I was under the impression that teflon needed to be etched with either a gas or some florene junk before it could be bonded. Sheets are sold pre-etched for that purpose. If that stuff etches ordinary teflon, Your Old Dog. I wonder if that would work to glue a similar material to my aluminum table saw fence? Boy would that be nice for ripping. It is true, there is nothing free about freedom, don't be so quick to give it away.

There's a teflon tape with adhesive already on it available from some woodworking suppliers. Cut to length, peel off the backing and stick it on. Not as good as epoxy, no doubt, but really nice for some applications. I haven't tried it for machine slides because the Turcite has a bronze filler that I think makes it hold up better. Evan - Thanks for the post - that's good info. PTFE Teflon has been around for quite a while. IIRC, the "breakthrough" that led to "non-stick" teflon cookware was figuring out how to make the "non-stick" stick to the aluminum pan.

Is it possible that a patent ran out on this technology, and that's why it's now available to us commoners? The curse of having precise measuring tools is being able to actually see how imperfect everything is. The patents on non-stick frying pans are long gone. Teflon was discovered in the 30s. The non-stick frying pan was first developed in France after WWII Tefal as Dupont wasn't at all interested in commercializing the technology at the consumer level.

The secret to making teflon stick to the pan is an etching process that makes the surface of the aluminum slightly porous allowing the teflon to mechanically interlock to the pan surface. Sodium will etch fluorocarbon polymers under the right conditions. A hydrogen and nitrogen plasma will work too - that's used when the plastic has to be electroplated.

I always bought etched sheets when I needed to glue teflon, and was too cheap to send the part out to get a teflon coat put on it. I'll have to try the Loctite item after my stash of etched sheet runs out. All rights reserved. Yes No. OK Cancel.
