I'm going to do a tubeless setup soon for the first time. Yes, I'm very slow to adopt new technologies. :-) But, as I researched sealants, I had a crazy idea. This paragraph from bikeradar sparked it:
Most sealants use the coagulating properties of natural latex to clog punctures. Latex is a dispersion of polymers (long chain molecules) in either water, or a water-based solution of ammonia. Inside a hole in the tyre, the air pressure drops and there is a rush of air. This causes the water/ammonia-solution to evaporate, leaving the latex molecules to coagulate (knit together), plugging the hole.
So, if we take this as correct, could the life of sealant be extended by adding a small amount of a water/ammonia solution to the tire, say, every week or so? I have no idea how much or what ratio. I have done some Googling on this, but haven't found much. I'll keep at it, but I'm curious if anyone here has heard of such a thing.
