Steel Putty
Epoxy Repair Compound
High-performance steel-reinforced epoxy putty for emergency pipe leak repairs, corrosion damage, and structural filling. Hardens to form a durable, machinable metal-like surface resistant to chemicals, water, and extreme temperatures.
Product Overview
Industrial-Grade
Epoxy Filler
Steel Putty is a two-component, steel-reinforced epoxy compound engineered for emergency repairs of leaking pipes, tanks, and equipment. The putty consistency allows for easy molding and gap filling, even on wet or slightly contaminated surfaces.
Once cured, it forms a hard, durable metal-like surface that can be drilled, tapped, machined, sanded, and painted. The steel-filled formulation provides excellent adhesion to metal substrates and superior resistance to chemicals, solvents, and thermal cycling.
Typical Applications
- Pipe leak sealing
- Corrosion pit filling
- Tank repair
- Valve body repair
- Pump casing repair
- Structural gap filling

Key Advantages
Why Choose Steel Putty?
Fast Emergency Repair
Sets in just 15 minutes at room temperature. Allows for immediate emergency intervention on active leaks without system shutdown or hot work permits.
Easy Application
No mixing tools required. Simply knead the two-component putty by hand like modeling clay and apply directly to the damaged area. Works on wet surfaces.
Metal-Like Hardness
Cures to a hard, durable surface that can be machined, drilled, tapped, filed, sanded, and painted. Bonds tenaciously to steel, iron, aluminum, and other metals.
Superior Strength
Compressive strength up to 4,000 PSI provides structural integrity for filling large gaps, corrosion pits, and thread damage. Withstands mechanical loads and vibration.
High Temperature
Continuous service temperature up to 150°C with short-term excursions to 300°C. Ideal for steam lines, hot water systems, and high-temperature process piping.
Cost-Effective
Significantly reduces repair costs by eliminating downtime, welding expenses, and replacement part procurement. One technician can complete most repairs in minutes.
Application Instructions
How to Apply
Steel Putty
Follow these simple steps for optimal repair performance. Surface preparation is critical for maximum adhesion and long-term durability.
For pressurized system repairs, always follow proper lockout/tagout procedures and relevant safety protocols. Steel Putty is intended for temporary or permanent non-pressurized repairs unless used in combination with composite wrap reinforcement.
Surface Preparation
Clean the damaged area thoroughly. Remove loose rust, scale, oil, and contaminants using a wire brush, grinder, or abrasive pad. For optimal adhesion, roughen smooth surfaces. Steel Putty can be applied to damp surfaces but works best on clean, dry substrates.
Mix Components
Cut off the required amount from the stick (ensure you cut through both layers). Knead the two components together by hand for 1-2 minutes until uniformly mixed and the color is consistent throughout. The putty will begin to warm slightly as the chemical reaction starts.
Apply & Shape
Apply the mixed putty to the repair area immediately. Press firmly to ensure good contact and fill all voids. Mold and shape to the desired contour. For leak sealing, press putty around and over the leak source. Apply in layers for deep repairs, allowing each layer to set before adding the next.
Allow to Cure
Steel Putty will set hard in approximately 15 minutes at 23°C. Full cure is achieved in 24 hours. Lower temperatures will extend cure times. Once fully cured, the repair can be machined, drilled, sanded, or painted as needed. For maximum strength, allow full cure before subjecting to mechanical loads.
