Epoxy putty
Description
Epoxy putty/filler refers bulked-epoxy adhesives that, when the components are mixed, will harden at room temperature. Prior to hardening, they typically have a clay-like consistency that can be kneaded, shaped and smoothed. After the epoxy is mixed with a hardener, an exothermic reaction occurs resulting in polymerization into a 'rock hard' compounds that can be sanded, cut, drilled, and painted. Formulations vary by manufacturers, but common fillers include: chalk, kaolin, fuller's earth or microballoons.
