Loctite PC 3473 – Metal putty

Loctite PC 3473 is a two-component, steel-filled epoxy repair compound designed for rebuilding, repairing, and restoring worn or damaged metal components. It delivers exceptional mechanical strength, excellent adhesion, and outstanding resistance to abrasion, corrosion, impact, and a wide range of industrial chemicals. After curing, the material can be machined, drilled, tapped, ground, or painted, making it ideal for permanent metal repairs and maintenance applications.

Loctite PC 3473 is formulated to restore the original dimensions of damaged equipment, helping extend the service life of critical components while reducing downtime and replacement costs. It bonds strongly to steel, cast iron, stainless steel, aluminum, and many other metal substrates, providing a durable repair that withstands demanding industrial operating conditions.

The epoxy compound is widely used in maintenance, repair, and overhaul (MRO) operations across industries such as manufacturing, mining, power generation, marine, oil and gas, chemical processing, and wastewater treatment. It is ideal for repairing cracked housings, worn shafts, bearing seats, pump casings, valve bodies, flanges, keyways, and other metal surfaces damaged by wear, corrosion, erosion, or impact.
