Product Description

PPG SigmaShield 400 is a two component, high solids, glass flake, reinforced polyamide cured, epoxy coating that offers long term protection in areas subject to wear and tear and can be applied in temperatures down to 10°C.

Best Uses

SigmaShield 400 can be used on steel and blasted steel and offers excellent abrasion and impact resistance in industrial and marine exposures. Sigmashield 400 is highly suited for use on ice-going vessels and offers extremely good corrosion resistance that protects the surface from natural damage caused by the environment.

Application

SigmaShield 400 can be applied easily and effectively using brush, roller or spray and has a good drying of 6 hours to touch. After 24 hours you will be able to apply a second coating which will reach full cure after 8 days. Once dry you will be provided with a glossy black finish, available in other colours on request.

Surface and Environment

SigmaShield 400 is highly suited for use in a marine type environment where protection against water and chemicals is vital. 460 offers very low water permeability due to the glass flake barrier and is suitable for immersion service.
