Thanks to the addition of microscopic silicate particles, Caffélatex moves slowly through holes, allowing the sealing ingredient more time to heal the puncture. These particles are not macroscopic (e.g., glitter 150-300 microns) but are instead microscopic, less than 2 microns in diameter. Thus, Caffélatex flow characteristics change on a microscopic level without the headaches of valve-clogging glitter. Puncture repair speed is especially noticeable with lightweight or thin-casing tires.
The first advantage of Caffélatex over classic latex-based sealants comes from a foaming behaviour, activated by wheel movement. Centrifugal force drives standard latex-based sealants against the outer circumference of the tyre. Caffélatex turns instead into foam, filling the tyre’s entire internal cavity, making our sealant much more effective against sidewall punctures. Caffélatex go back to liquid state after around 15 minutes of stillness.
Fast sealing action makes it ideal for mtb and road tubeless, tubular and standard tyres. Caffélatex repairs punctures up to 5 mm (mtb tubeless) and 3 mm (road tubeless).
Caffélatex is a very stable and durable sealant, although its lifespan is also dependant on kind of application and external conditions.
Using the recommended quantities for tyre size, the expected sealant lifespan is:
- Tubular (or inserted into latex/butyl inner tube): up to 1 year
- UST Tubeless tyre: 2-6 months
- Tubeless-ready tyre: 1-4 months
- Tube-type tyre: 1-3 months
Nevertheless, in the impossibility of knowing our customers’ specific application (kind of wheel/tyre set-up, tyre sidewall thickness and porosities, external temperature and humidity, bicycle storage conditions…), we recommend checking Caffélatex every 2 months, to make sure it’s liquid and therefore retains its ‘puncture preventive’ action.
When dry, Caffélatex-sealed wheels are still air-tight, but Caffélatex won’t actively repair punctures.
Completely ammonia-free, it’s 100% tyre and rim friendly and also the favourite sealant for cyclocross/tubular applications, creating no harm to the sensitive latex innertubes.
