Permatex 84109 Multi-metal Epoxy Steel Weld 0.84 Fl Oz

Product Description

The PERMATEX 84109 is a multi-metal epoxy adhesive formulated for bonding, filling, and rebuilding metal surfaces. Packaged in a dual-syringe applicator, it dispenses a two-part epoxy that mixes and cures to a hard, grey finish capable of being drilled, tapped, filed, and sanded. It delivers a working time of 4 to 5 minutes and reaches fixture strength in 8 to 10 minutes. The cured bond handles continuous service from -60 degrees F to 300 degrees F and intermittent exposure up to 350 degrees F. HVAC technicians, plumbers, electricians, and general trade professionals use this product for metal repair and bonding tasks in the field or shop.

The 84109 is suited for repairs and fabrication work involving steel, iron, aluminum, copper, brass, and other common metals. Typical applications include patching cracks or voids in metal housings, rebuilding stripped threads, filling pinholes, and securing metal components where welding is not practical. The compact 0.84 fl oz dual-syringe format makes it convenient for service vans and job-site toolboxes. It is carded for single-unit retail and trade counter distribution.

Installation Notes

Surface preparation is critical for epoxy adhesion — clean, degrease, and abrade mating surfaces before applying. Dispense equal amounts from both syringe barrels and mix thoroughly on a disposable surface before applying to the repair area. Allow full cure before returning the repaired component to service or applying mechanical load. Follow all applicable safety data sheet guidelines for ventilation and skin contact when handling uncured epoxy.
