LOCTITE® EA 3471 is a two-part, non-sagging, steel-reinforced epoxy repair putty that cures to a metal-like finish. It is designed for easy application without the need for heating or welding and can be machined, drilled, tapped, or filed after curing. This product is ideal for repairing non-structural defects in castings, making jigs and fixtures, sealing vessels, tanks, and valves, resurfacing worn air seals, and filling cavitated areas. It operates effectively within a temperature range of -30°C to +105°C (-22°F to 221°F).
- Cures to a metal-like finish
- Superior adhesion on metal surfaces
- Bonds well to all metal substrates
- Will not sag or shrink
- Rebuilds worn parts quickly
