Hi! I am over from re.bike.tech where exists a gizmo called a self sealing tube filled with latex,water, and fiber to jam the puncture solid. Between tire and tube is placed a smooth surfaced plastic liner resisting incoming debris passing through the tire and a seal for latex/water coming from the puncture, The latex/water does not ?set up.' The air seal maintained by the fluid film between liner and tube.
QUESTION IS there a substance available (around the house and shop) compatible with the latex/water fluid that would ameliorate the desired effect of keeping air in the tube? One could dust it on doing a dual role of lubricating the tube as with the usually recommended talc application or sprinkled on dual stick tape and applied to the liner? possibly setting up in a jello like substance?
Bentonite was the first that came to mind here then arrowroot, cornstarch?
