Description
LOCTITE EA 3471 500G – Steel-Filled Epoxy Putty for Industrial Metal Repairs
LOCTITE EA 3471 500G, also known as FIXMASTER STEEL PUTTY, is a two-component steel-reinforced epoxy repair compound designed for rebuilding worn or damaged metal parts. Once cured, it forms a metal-like surface that can be drilled, tapped, filed, or machined. With excellent adhesion, mechanical resistance, and easy application, LOCTITE EA 3471 is an essential product for maintenance, repair, and industrial servicing.
Applications of LOCTITE EA 3471
- Non-structural repairs of metal castings

Storage Recommendations
LOCTITE EA 3471 should be stored in its original, tightly sealed container in a dry location at +8°C. Storage below +21°C or above +28°C may adversely affect performance. Do not return removed material to the container to avoid contamination. After use, clean tools with LOCTITE 7070, acetone, or isopropyl alcohol before the compound hardens.
