Improved formula (since January 2012): thanks to the addition of microscopic silicate particles, Caffélatex now moves more slowly through holes, allowing the sealing ingredient more time to heal the puncture. These particles are NOT the macro-size (e.g., glitter 150-300 microns) but rather 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 up to 5 times faster, an improvement 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, but we know this is highly depending on kind of application and external conditions. During our field-testing it stayed liquid for over 12 months in thick-casing tubeless tyres on UST wheels. 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.
Not corrosive: being completely ammonia-free, its 100% tyre and rim friendly. It’s also a favourite sealant for cyclocross/tubular applications, creating no harm to the sensitive latex innertubes.
Usage and storage temperatures: from very cold to very hot, exceeding by far those of first-generation latex sealants (usage: -20/+50°C ~ storage: -15/ +30°C).
Recommended quantities: 30 to 50 ml per wheel for road/cyclo-cross applications; 50 ml for mtb tyres up to 26×2.10/29×2.00; 60 to 100 ml for mtb tyres over 26×2.10/29×2.00.
