Sylmasta Industrial Metal – Two-Part Metal-Filled Epoxy Paste
Industrial Metal is a metal-filled, two-part repair compound designed for fast, durable maintenance on metal and many other substrates. The thixotropic paste is easy to mix and apply, will not sag, and cures even on wet surfaces—including underwater—making it ideal for sealing and rebuilding worn or damaged areas on pumps, valves, castings, tanks, and low-pressure pipework. Once cured it can be machined, drilled, and tapped, providing long-term protection against corrosion and chemical attack.
Key Features
- Cures on wet surfaces and underwater for emergency and submerged repairs.
- Metal-filled, thixotropic paste—no slump on vertical or overhead areas.
- Easy 2:1 mix; light consistency mixes easier than heavy epoxy pastes.
- Machine, drill, and tap after full cure; hard, smooth, corrosion-resistant finish.
- High mechanical strength with excellent chemical resistance.
- Virtually odourless; zero solvents (100% non-volatile content).
- Long working time for shaping and profile rebuilds.
Applications
- Repair holes, cracks, and pitting in metal tanks and low-pressure pipes.
- Rebuild worn areas in pumps, valves, housings, and flanges.
- Bonding and patching on metals, wood, and most plastics.
- Marine, water utility, and plant maintenance where moisture is present.
- Automotive bodywork and general fabrication repairs.

Frequently Asked Questions
What surface preparation is required?
Clean, degrease, and mechanically roughen to a defined edge (do not feather-edge). For best adhesion, grit-blast to white metal and solvent-wipe. For salt-exposed metals, blast, high-pressure water-wash, let “sweat,” and repeat until soluble salts are ≤40 ppm.
Can it be applied underwater?
Yes. Industrial Metal is moisture tolerant and can cure underwater, making it suitable for submerged or splash-zone repairs.
How do I bridge larger holes?
Use fiberglass, sheet metal, or wire mesh as a backer and spread the epoxy to encapsulate and rebuild the profile.
What are the post-cure steps for maximum heat resistance?
Room-cure 24 hours, then heat at 80°C for 2 hours, followed by 130°C for 3 hours; allow to cool.
When can I machine the repair?
After full cure (~24 hours at room temperature). The metal-platelet reinforcement allows a smoother machined finish compared to standard pastes.
Where can it be used?
Metals, wood, and most plastics on pumps, valves, housings, tanks, and low-pressure pipework in plant, marine, and utility environments.
