Rectorseal 97606 4-Ounce Ep-400 Epoxy Putty
Rectorseal is an industrial supply company, providing specialized products for the building and maintenance trades. They give us a little more to work with, by packaging their epoxy putting in a four ounce tube, rather than the conventional two ounces (they also have two ounces if you want). This is a fast-acting epoxy putty that fully hardens in 15 to 20 minutes, a third to a quarter of the time that its competitors do. You'll have to work quickly with it, but you won't have to wait a long time for it to cure. Once cured, it can be machined, sanded, painted and tapped. This epoxy putty can withstand temperatures up to 500 degrees and has been pressure tested to 1300 PSI.
