Subject: Re: [CR] tubular tire glue


Hello List, Similar situation in Germany, some shops and mechanics use and recommend automotive glue made by Teroson. It is originally used for glueing fabrics and rubber mostly in a cars interior. It is also used for glueing rubber seals in doors of cars etc. It comes in a 500ml tin and ist applicated best with a brush. The correct name is Terokal Profilgummikleber 2444. I have bought a tin quite cheaply on ebay and used it for most of my tires without a problem. I also bought a matching thinner, since once opened the glue tends to get thicker due to dissolution of the solvent in the glue. I have heard that some Pro mecahnics use it also and i vaguely remember seeing a team Mechanic of Team Milram using it in a TV programm, but i might be wrong there.

3M Fast Tack was a well known domestic alternative to the French and Italian tubular glues in the period you speak of. It was just so much easier to walk into any local auto parts store and pick up a fresh tube of "3M" than to explain what you were looking for at the LBS, hoping they can order it. Many tests were done by cycling publications at the time and 3M Fast Tack was judged as good or better than the proprietary tubular glues. In the early 1970s I was still into motorcycle racing before going back to cycling and I recall "3M" and duct tape being indispensable for everything from fixing cracked gas tanks and torn leathers to securing nuts and bolts. I also remember various other yellow glues from 3M used in industrial applications which worked and smelled the same and may well have been the same stuff with a different part number to serve a different market. In fact, the same kind of 3M adhesive is still around today, but it's probably not the same formulation as the original.

And that's the rub. Over the years, environmental and health concerns have dictated changes in the formulation of these adhesives over the years. While they still work great in the applications the manufacturer intended, they may not be so good anymore for spin-off applications, such as tubular tire glue. Somewhere I read that the solvents now used in 3M Fast Tack will migrate through the base tape and soften the adhesive between the base tape and the tire casing, letting the tire roll off while the base tape is still securely attached attached to the rim. That's the reason it's no longer recommended. -- John Betmanis Woodstock, Ontario Canada
