PPG Sigmashield 400 Amerlock 400 GF is a two component, high solids glass flake reinforced polyamine cured epoxy coating for steel, metals, concrete and masonry.
PPG Sigmashield 400 / Amerlock 400 GF is designed to prevent corrosion under insulation (CUI) of carbon steel and stainless steel. PPG Amerlock 400 GF is glass flake reinforced for improved impact and abrasion resistance with excellent resistance to corrosion. Ideal for long term protection of areas subject to heavy wear and tear.
Suitable for application to carbon steel, concrete, masonry, galvanised steel or non ferrous metals and stainless steel.
- Very low water permeability due to glass flake barrier
- Suitable for immersion service
- Designed to prevent corrosion under insulation of carbon steel and stainless steel
- Up to 750 microns DFT in a single coat
Remove all loose paint, mill scale and rust. The surface to be coated must be stable and free from grease, oil and all foreign materials. For immersion service, blast clean to ISO Sa2.5. For atmospheric service, abrasive blast clean to ISO-St2. Apply using airless spray or conventional spray. Use brush or roller for touch up and spot repair only.
