Pro poxy 20 is a fast acting, co-extruded single stick, epoxy putty. Made of a pre-measured, steel reinforced dark gray/black epoxy resin with a contrasting strip of hardener embedded in the center. The two part epoxy compound mixes quickly and easily to form a permanent steel-hard bond in 20 minutes. Adheres to almost any surface with strength often greater than the materials it has joined. After curing, it can be drilled, filed, sanded, painted, and machined. Can be applied to damp or wet surfaces and even makes underwater repairs. Pro poxy 20 is non-conductive and may be used for electrical insulating repairs and can be used on applications where it is subject to temperatures up to 300 deg F for extended periods of time. Do not expose to open flame.
