It's been said there's an exception to every rule ...we'll see! The rule being this time.. "there are no stupid questions". This may be it! I was wondering is there a glue, some adhesive that sticks to teflon. I have some cool teflon sheet and I'd like it to lay relatively flat to a platen and stay there. Any suggestions besides..... "eat **** and die"!!  What's the exception to the rule "there's an exception to every rule"

Hey Billy! Well, if you scuff up the teflon sheet you can use JB weld or you can try Loctite plastics bonding system |

What kind of teflon is it? What are the shape/geometry of the parts? What kind of load will the adhesive joint see? shear, dynamic etc... Teflon is known for not sticking to anything. This is almost like asking what material is not subject to gravity. Stupid question, no, but maybe a stupid idea to try, depending on the application. |

I've used contact cement to adhere UHMW to the edge of cabinet grade plywood on the base of my router table. It's under constant compression from the weight of the table but it's never come loose while sliding the table across the rough concrete floor of my garage. Kevin Looker |

How about this http://www.shop3m.com/3m-300lse-high-st ... 5x89d.html I believe this is similar to what you will find pre-applied to Teflon slick strips for saw fences and such. |

You might consider a two-sided tape with a silicone adhesive. For that matter I don't see why an acrylic transfer adhesive wouldn't hold teflon. Even though the actual adhesion might not be stellar....you may have enough joining area to make up for it. It kinda depends on how it's going to be used...how the forces affecting the bond are applied. Otherwise there are spreadable liquid silicone adhesives that are meant specifically for bonding high temperature silicone heating pads to aluminum or steel tooling surfaces. These would likely hold teflon or UHMW as well as silicone. Anyway....there are no stupid questions....just stupid assumptions. |

Why not bolt it down? Is the platen ferrous? Then you could simply drill some holes in the teflon (use a Forstner to get a flat bottom hole), and drop in some rare earth magnets. |

Double-stick tape, or the pressure sensitive adhesive that is used to attach pickguards (I use 3M 465). |

There are a few different types of teflon. Not sure what you have. In my line of work, industrial slide plates are made using mostly glass filled teflon. Nasty chemicals not available to the public are used to etch the teflon to provide a tooth. Epoxy is then used to bond it to steel plates. You might try scratching or roughening the surface to provide a tooth and then trying epoxy. No matter what adhesive is used, it will never develop the full strength of the parent material. |

Thanks guys! Great suggestions! I just kind of threw this out there because I have a good size roll of 32nd sheet and I wanted to find use for it. Now I have! Thanks again!! |
