J.C. Whitlam’s TALON epoxy putty is a hand-mixable, single stick, fast-setting putty. After mixing, the epoxy forms a polymer compound that can be molded, wrapped around, or used to build up and repair leaking pipe, ductwork, small parts and more. After two to three hours, the putty for plastic can be filed, drilled, sanded and painted. After 60 min., the putty for steel can be drilled, tapped, machined, ground, filed and painted. J.C.
