Caffélatex, valves and inner tubes

Being a synthetic latex, Caffélatex is not as intrinsically “sticky” as natural latex sealants, showing a lower tendency to clog valves and valve mechanisms. Still, it’s important to learn how to use it properly to take full advantage of the puncture protection, reducing the drawbacks to the minimum. General tips for long lasting valves, when … Continued

Caffélatex and the “hair dryer” effect

Beside the use of CO2 (described here) or contamination/mixing of your sealant with other products (described here), the “hair dryer” effect is a common but seldom recognized reason of sealant reduced life span. When it happens: trying to inflate with an air compressor a “difficult” tubeless tyre, it’s easy to insist, blowing air (and here … Continued

The right Caffélatex quantity for mountain, fat, road, cyclocross

Tyre sealants are a must for the performance-oriented cyclist, to avoid unplanned stops before the finish line because of punctures. The big question is: how much sealant is the right quantity? Parameters influencing the correct sealant quantity: Several parameters should to be evaluated, for example: external humidity temperature frequency of tyre inflation … but the … Continued

A Caffélatex cocktail

We talk from Caffélatex standpoint, but what we’re analyzing here generally applies to “latex” (synthetic or natural) sealants. The common reasons of sealant polymerization can be divided into two groups: physical (related to temperature changes, evaporation…) or chemical. Physical: a sudden drop of temperature, as with CO2 cartridges, described here; a quick evaporation, that’s what … Continued

Caffélatex and tubulars

No aggressive chemicals: its complete lack of ammonia or aggressive chemicals make Caffélatex benign even with very sensitive latex inner-tubes (like those found on professional level cyclocross tubulars, for example). Caffélatex is perfectly compatible with tubulars with butyl tubes or tubeless-tubulars construction (like Tufo). Long expected lifespan: if used inside tubulars, as their porosity is … Continued

Caffélatex and CO2

While Caffélatex resists well to both low and high temperatures, the sudden (and localized) change of temperature is not good for its stability. A strong thermal shock could indeed be a polymerisation-starter for any latex-based sealant (natural or synthetic), so we suggest to limit the use of CO2 cartridge or, if needed, to do it … Continued
