JB "Weld" is just overpriced EPOXY.

As usual when it comes to anything involving chemistry, you don't know
what the hell you're talking about. Yes, it's epoxy-based -- but
that's not all it is. Google up the MSDS on JB Weld. Then tell me that
calcium carbonate, iron powder, and magnesium silicate are normal
constituents in most epoxies.


Epoxies used for gluing have fillers of all sorts.
Fillers don't do anything to increase the bonding ability;that comes from
the chemistry of the epoxy itself.Same for hi-temperature endurance.

For some good info on epoxies;www.systemthree.com,read The Epoxy Book;you
can download it for free.
