Effetto Mariposa Caffelatex Tire Sealant

Size

Caffelatex is the innovating foaming tire sealant from Effetto Mariposa - a must have in any cyclocross pit bag or toolbox. It offers a unique advantage compared to other brands: Actifoam™, a foaming agent activated by wheel movement. This foaming action makes it fill the entire internal cavity of your tire or tube, making it much more effective against sidewall punctures. 

Caffelatex works both for repairs and also as a preventative. You can use it for both tubeless and tubular applications. It contains no ammonia and is thus 100% tire and rim friendly. 

Dugast, the manufacturer of some of the finest tubular tires one can buy for cyclocross, are very concerned about latex inner tubes interacting with tire sealants. Over the years they have received warranty claims where the inner tube of a tubular tire has been "cooked" by latex-based sealants. What do they say about Caffelatex? Thumbs up:

"Racers have extensively field tested Caffélatex with our tubulars. The result is excellent, it's the only sealant we recommend to our customers". - A. Dugast 

Caffelatex is flexible and can work from very cold to very hot temperatures, ideal for the bitter cold of January cyclocross.

Frequently Asked Questions about Caffelatex: 

 

Q: Why is such a product needed?
A: There were several aspects of current tire sealants that we (Effetto Mariposa) felt we could improve. We wanted a sealant to be more effective (being able to be there and everywhere in the tire when punctures occurred), more stable in time and temperature, without any chemical potentially dangerous for tire/rim.

Q: How much easier is it to set up a tubeless tire?
A: Tubeless conversion of standard tires has a lot to do with the tire you're using and its bead diameter. Once inflated, a better sealant will seal the tire faster, but has a lesser influence on the primary inflation (where bead diameter/rim used play a major role, instead).

Q: Do you intend it to be used like Stan's Notubes, both as a sealant as well as to allow tube type tires to be run with out tubes?
A: Yes. We officially recommend Caffélatex sealant and KIT for Tubeless Ready (Hutchinson, Bontrager, Specialized...) or TNT (Geax) tires, where beads are tubeless-like. Caffélatex Tubeless Tape is quite thin, and for the tubeless conversion of standard tube-type tires a compressor is going to be a must. The advantage of Caffélatex Tape, beside the low weight and resistance, is that it's easy to mount TR and TNT tyres on 'converted' rims, something very difficult using rubber sealing rim-strips.

Q: In motorcycles there are similar products, foaming tire sealants, is this an adoption of that?
A: The base formulation we started with to develop Caffélatex comes from the automotive field, where sealant stability, effectiveness and chemical compatibility have very high requirements.

Q: How important was it to get the ammonia out?
A: Very important. That obliged us to stay away from natural latex formulations and turn to synthetic latex, which has some other advantages as well. The ammonia content of current latex sealants is not dangerous for tires/rims in the short period... but some concerns start to be raised from long-term users. We prefer to avoid any of these potential problems from the start.

Q: Will it dry up as fast as other latex-based sealants?
A: Synthetic latex lasts longer than natural latex... although it's difficult to give numbers here, it depends a lot on tire/wheel/external conditions. During our field-testing Caffélatex has stayed liquid over 12 months in thick-casing tubeless tyres on UST wheels. Nevertheless, in the impossibility of knowing our customers' specific application (kind of wheel/tire 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.

Q: If I use CO2 cartridges with CaffeLatex will it freeze?
A: Caffélatex won't coagulate or freeze (it can go as low as -20°C in its liquid form).

 

With 3 sizes available, you can get just the right amount - a large container to keep in your shop, or small portable single-use sizes that are perfect for your back pocket on long training rides.
