Loctite EA 3478 – Epoxy putty
Loctite EA 3478 is a two-component, steel-filled epoxy repair compound designed for rebuilding, repairing, and restoring worn or damaged metal components. It provides exceptional mechanical strength, excellent adhesion to metal surfaces, and outstanding resistance to abrasion, corrosion, chemicals, and impact. Once cured, the material can be machined, drilled, tapped, or ground, making it ideal for permanent industrial repairs.
The epoxy is formulated to restore the original dimensions of damaged equipment, reducing the need for costly replacement parts and minimizing production downtime. It bonds strongly to steel, cast iron, aluminum, stainless steel, and many other metal substrates, creating a durable repair that withstands demanding operating conditions.
Loctite EA 3478 is widely used in maintenance, repair, and overhaul (MRO) applications across industries such as manufacturing, mining, power generation, marine, oil and gas, and process plants. It is ideal for repairing cracked housings, worn shafts, pump casings, bearing seats, keyways, flanges, valves, and other metal components exposed to wear and corrosion.
