Liquid Metal is an epoxy coating with high corrosion resistance used to paint protective layers onto machine parts, metalwork and pipes

Liquid Metal Epoxy Coating

Coating a pipe with Liquid Metal prevents the original line becoming weakened. Liquid Metal also protects against damage caused by internal corrosion by creating an impermeable membrane around pipework, capable of withstanding future breaches of the line from inside and containing pipe content.

When making a repair with a SylWrap Pipe Repair Bandage, a coating of Liquid Metal added to the pipe before the bandage improves surface adhesion between the pipeline surface and composite wrap.

This subsequently increases the effectiveness of the protective layer provided by the bandage. When applied in conjunction with SylWrap, Liquid Metal can be used as a load-transfer layer providing PCC-2 compliant repairs.

Away from pipe repair, Liquid Metal is used as an adhesive for re-gritting floors and other surfaces, pouring into moulds to create metal casts, and for the maintenance and repair of tanks, pumps, valves, flanges, engines, and impellers. It can be easily machined.

A 90-minute gel time allows for large quantities to be mixed and carefully applied without the threat of premature curing. Because of its work time, Sylmasta recommend Liquid Metal for applications taking place at higher ambient temperatures.

Liquid Metal Epoxy Coating Details

Before applying Liquid Metal, surfaces should be free of paint, rust and grime before being roughened up through either grit blasting or grinding with a coarse wheel or abrasive disk pad.

Full instructions detailing the preparation process can be found on the Technical Data Sheet and are provided with the product.

Liquid Metal should be applied as soon as the preparation procedure is completed. Part A and Part B are mixed at a 3:1 ratio by volume or a 5:1 ratio by weight.

To ease the mixing process, the Liquid Metal Part A container has enough room to dispense all Part B into, enabling it to be applied with a brush straight from the container.

The epoxy is brush applied and each coating should be 0.5-1mm thick. To ensure a pinhole-free coating, at least two coats are needed.

Liquid Metal has a gel time of 90 minutes. The re-coating time between coats is approximately 5–8 hours after applying. A full cure is achieved 24 hours after the final coat.

When adding a SylWrap Bandage in pipe repair applications, the bandage is applied once the coating of Liquid Metal has gelled but remains tacky.

To determine the quantity of Liquid Metal needed for a specific pipe repair application, please go to the Repair Calculator Tab and enter your repair data.

The light consistency of Liquid Metal makes it easy to mix and apply with little sag. It is virtually odourless, with no unpleasant smell, can be easily machined and is temperature resistant to 150°C.

Liquid Metal is temperature resistant to 150°C. For protecting pipework and surfaces exposed to extreme temperatures in excess of 150°C, please see Titanium Supergrade HT Epoxy Paste.

With Liquid Metal not effective underwater, Sylmasta recommend SylWrap CR Corrosion Protection Wrap for the protection of pipes and structures in marine environments.

SylWrap CR is a specialist composite repair wrap infused with highly effective corrosion inhibitors which is applied directly underwater.

Benefits of Liquid Metal

Liquid Metal Epoxy Coating Repair Calculator

The below Liquid Metal & Ceramic Brushable Coverage Calculator can be used to determine the quantity of Liquid Metal needed to coat a specific pipe, cylinder or surface area.

Enter the diameter of the pipe or the width of the repair area in millimetres, the length of the repair area and the coating thickness of Liquid Metal to be applied. The wastage percentage is how much Liquid Metal you expect to lose in the application.

Once you have entered your data, the calculator will show the amount of Liquid Metal required in kilograms. If you require further help with an application, please fill in the report form at the bottom of the calculation and a Sylmasta technician will get back to you.
