Which Puncture Patches?
Postby TonyMax » Sat Mar 21, 2015 2:42 pm
Should I look for self adhesive ones or the ones that use glue?
I'm thinking buying in bulk from eBay would be the way to go?
Cheers,
Tony

Standard cheapo self-vulcanising patches with rubber glue work best.

Better than getting let down by failed patches at the most inopportune times.
For all the effort patching old tubes, only to have it fail coming down a hill or on an unlit road at night ...
Patches are a fools game ...you wont win.

Sounds like you've had a bad off from a failure. I can definitely sympathise with your position.Derny Driver wrote:Ive had bad patch experiences and have been mentally scarred by them.
I've had failures with cheap tubes. Fortunately, caught before I got into an awkward situation.

From Wikipedia,bychosis wrote:Not sure, but my understanding is that the modern patch kits aren't technically a vulcanising patch, but a chemical bond using adhesive. Vulcanising patches used to use flame/heat to bond the patch to the tube. modern patching is just as effective, a whole lot safer but not actually vulcanising as I understand it. Vulcanising is the process of hardening natural rubber to a usable product. /pedant
Some more interesting info on different cement types here:Rubber cement is simply a mixture of solid rubber in a volatile solvent that will dissolve it. When the cement is applied, the solvent evaporates, leaving the rubber as the adhesive. Almost any rubber (pre-vulcanized or not) can be used. [1] The rubbers used might be natural rubber, gum mastic or gum arabic. Early solvents used included chloroform and benzene. [2] In the United States of America, current formulations include n-heptane. In the UK, a product called Marabu-Fixogum uses acetone.
Special compositions[edit]
Many compositions have included hardeners and/or vulcanizing agents designed to improve the cohesion of the rubber.

For emergencies I carry a spare tube and the self-adhesive patches, the latter of which I've yet to use (touch wood).

Common error with proper rubber patches is that people forget to rough up the surface of the tube with sandpaper or the little metal file before applying glue.
Also glue on both patch and tube and let dry for a minute or as I do blow on the glue until it is no longer clear.
I also bought a big tube of rubber cement from the auto shop, it is better than those little tubes.

Don't use the self glues patches, they perish after a time.Bentnose wrote:Haven't heard of gluing the patch
Get the proper rubber patches in the little kit.

I've picked up a number of discarded tubes over the years and patched them, all good.
Never had a rapid failure of a patch. I've had the rare occasional slow leak is all.

EDIT: actually, all of mine have also been lower pressure MTB or commuter. Not a high pressure road bike tube. Maybe that's the difference?

the stick on patch for the tube never failed and lasted at least 1 year.
