Caffélatex is a truly innovative tyre sealant, successfully used on and off (mtb, cyclocross) road, for tubeless, tubular and inner-tube applications. CHARACTERISTICS: How it works: 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 of macroscopic size (e.g., glitter 150-300 microns) but are instead microscopic particles 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. Foaming action activated by wheel movement: the first advantage of Caffélatex over classic latex-based sealants comes from a foaming agent (Actifoam™), activated by wheel movement. Centrifugal force drives standard latex-based sealants against the outer circumference of the tyre. Caffélatex foaming action causes it to fill the tyre’s entire internal cavity , making it much more effective against sidewall punctures. Puncture-repairing action: its fast sealing action makes Caffélatex ideal for MTB and road tubeless, tubular and standard tyres. Caffélatex repairs punctures up to 5 mm (mtb) and 3 mm (road). Stable over time: thanks to its formula, 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 Caffélatex inserted into latex/butyl inner tube): 1-2 years. UST Tubeless tyre: 4-6 months. Tubeless-ready tyre: 2-4 months. Tube-type tyre: 2-3 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.
