LOCTITE epoxy putty is a versatile repair material designed for filling gaps, sealing leaks, and repairing damaged metal and other compatible surfaces. It provides strong adhesion and durable repairs for industrial maintenance, machinery, equipment, and general repair applications. Depending on the formulation, LOCTITE epoxy putties can offer resistance to chemicals, moisture, and demanding service conditions. Choose the appropriate product based on the substrate, operating temperature, chemical exposure, and repair requirements.

Rebuilding Metal Surfaces

Sealing Critical Leaks

Gap Filling & Casting Repair

Restores scored hydraulic rams, worn shaft journals, stripped keyways, and cracked engine blocks with steel and aluminum filled putties that machine like host metal.

Fast-setting emergency formulations cure under damp conditions to isolate pinhole pipe ruptures, corroded elbow joints, and leaking storage tanks without hot work.

High-density epoxy paste bridges wide structural tolerances, fills porosity defects in new castings, and provides long-term galvanic isolation between dissimilar metals.

Selecting Your Formulation

Substrate Compatibility

Thermal & Chemical Exposure

Working Time & Machinability

Match steel, stainless, aluminum, bronze, or wet-surface base polymers to ensure thermal expansion parity and prevent galvanic contact corrosion.

Verify operating environments against continuous temperature limits, intermittent thermal spikes, and direct immersion in cutting oils, fuels, or caustic washes.

Balance 5-minute emergency stick repairs against machinable 30-minute working putties that can be drilled, tapped, turned, and ground to precise tolerance.
