Interesting caulking
« on: October 13, 2011, 05:09:45 PM »
   In the process of doing repairs to an EDPM trailer roof, I ran across a caulking that  may have other uses.
Made by dicor, it's classed as a self leveling sealant. That basically means that it is not thick.   Anyway, I was
fairly impressed with it, so did a bit of destructive testing.  Two pieces of 1 1/4 flat bar, sand blasted about
two inches of the ends of both.  (kind of magnet size)  Applied caulk, lightly clamped for a couple of days.
Tried to get them apart by twisting etc. and was actually getting some deflection in the bars.
I don't think it would actually hold the magnets firm enough, as it's cured state is rubbery. But it may have
some applications for keeping the moisture out.
   Naptha is the solvent, so caution is advised.
Anyway, leaving the bars out in the weather this winter to see the effects.  Will post.
P.S. p/n 502-lsw for standard caulk tube.

Hey Rover.  In a word, no.  But if you give some guidelines, I'd be happy to experiment.
