Is Lexel a superior alternative to silicone?
I got this tube of Lexel for
the 5
gallon bucket solar hot water experiment thinking that the extra cost
would be worth it if it was indeed a "superior alternative" to silicone.
The main problem I had with
it was the amount of time it takes to dry. Expect to wait 1 to 2 days
for it to cure and 1 to 2 weeks before you reach "total firmness".
Lexel might be the better
choice if you need some extra elasticity, but I like a good old
fashioned tube of silicone that can be expected to dry and be ready to
use within hours depending on temperature and humidity.

According to their own MSDS:
Pretty much all of this will evaporate or leach out over time.
Better wear a half-mask respirator with activated carbon filters when using this indoors.
Silicone is pretty much harmless. Even the two component versions often don't have to be labelled as chemicals.
(silicones are also employed in non-stick cookware)
