Rectorseal EP-400 epoxy putty is a pre-measured kneadable reinforced epoxy putty stick that cures "steel-hard" within 15 to 20 minutes of mixing at room temperature (77 degree F). The epoxy is extremely tough and durable with exceptional adhesion to a wide range of surfaces.
Within an hour, it can be drilled, tapped, sanded, painted, filed or machined. It can be used to bond, seal, plug, mold or rebuild many different surfaces. The epoxy is capable of withstanding temperatures up to 500 degree F and will even harden under water.
