Sylmasta Liquid Metal Epoxy Coating – 4 x 500g
Liquid Metal is a low-viscosity, metal-filled two-part epoxy that brushes on to protect steel and other metals from corrosion and chemical attack. It provides a smooth, wear-resistant, low-friction finish and is easy to mix and apply with little sag. Use as a protective coating on pumps, impellers, flange faces, valves, castings, tanks, and pipework, or as a load-transfer layer before overwrapping with composite bandages. This item is the 4 x 500g kit.
Key Features
- Brush-applied, metal-filled epoxy forms a corrosion and wear resistant finish.
- Low viscosity with little sag for clean application on vertical surfaces.
- Solvent-free, 100 percent non-volatile; virtually odourless.
- Long working time for larger areas; gel time about 90 minutes (regular grade).
- Can be machined after cure; smooth, low-friction surface.
- Acts as a load-transfer layer prior to composite overwraps on pipes.
- Post-cure improves heat resistance for high temperature service.
Applications
- Protective coating for pumps, impellers, flange faces, water box ends, valves, castings, pipe elbows, and tanks.
- Pipe reinforcement: corrosion barrier and load-transfer layer before composite bandage overwraps.
- Bonding silicon carbide grit to ramps and floors for non-slip surfaces.
- General metal repair and protection on steel and most plastics.

Frequently Asked Questions
How is Liquid Metal applied?
Mix resin and hardener, then brush on 0.5–1.0 mm per coat. Apply at least two coats with a 4–8 hour recoat window to ensure a pinhole-free film.
Can I speed up the cure?
Yes. After an initial room cure, heat to accelerate. For maximum heat resistance, post-cure 24 hours at room temperature, then 80°C for 2 hours followed by 150°C for 3 hours, and allow to cool.
What preparation gives best adhesion?
Abrasive blast or grind to clean, bright metal. For salt-exposed steel, blast and high-pressure wash, allow to sweat overnight, repeat until soluble salts are ≤40 ppm, then solvent clean.
Where is it most useful?
Corrosion and chemical protection on pumps, impellers, flange faces, valves, tanks, and pipework, and as a load-transfer layer prior to composite bandage overwraps.
Is it solvent free and low odour?
Yes. It is solvent free with 100 percent non-volatile content and is virtually odourless during application.
