Devcon HR-300 Heat Resistance Steel Putty 500g (Product Code: 16301)

Devcon HR-300 Heat Resistance Steel Putty 500g (Product Code: 16301)

Stop leaks and repair heat-damaged equipment without shutting down your operation.

Devcon HR-300 is a heavy-duty, steel-filled epoxy putty engineered for high-temperature repair and reinforcement of metal surfaces. Whether you're dealing with leaking pipes, cracked engine blocks, or corroded steam lines — HR-300 bonds permanently to metal and withstands continuous heat up to 150°C with a maximum tolerance of 250°C.

Unlike ordinary epoxy putties, HR-300 is a no-sag formula that stays put on vertical and overhead surfaces, making it ideal for on-site repairs without dismantling equipment.

Key Specifications:

• Temperature resistance: Up to 150°C continuous / 250°C maximum
• Colour: Dark grey
• Net weight: 500g
• Cure time: 16 hours at 25°C
• Finish: Machinable, drillable after full cure

Why Workshops & Engineers Choose Devcon HR-300:

• ✅ No-sag formula — applies cleanly to vertical surfaces, pipes, and curved sections
• ✅ Strong metal-to-metal adhesion — bonds directly to steel, cast iron, aluminium and most metals
• ✅ Waterproof and oil resistant — holds up in wet, oily, and chemically exposed environments
• ✅ Heat resistant — purpose-built for hot zones where standard epoxies fail
• ✅ Permanent fix — machines, drills, files, and paints after curing

Typical Applications:

• Sealing leaks in heated pipes, valves, flanges, and valve connectors
• Repairing cracks and filling holes in engine blocks and crankcases
• Corrosion repair on steam piping and industrial tanks
• Reinforcing mechanical components exposed to thermal cycling
• Emergency repair of heat exchangers and boiler components
