Product Description

This product has London Underground 1255 approval.
SigmaCover 400 is a high performance, two-pack coating which is suitable for concrete and metal floors as well metal pipes and structural steel. Formerly known as SigmaCover 640, SigmaCover 400 is a self-priming, universal epoxy which has good adhesion on most coatings. SigmaCover 400 is available in a choice of colours, with a semi-gloss finish.
Best Uses
PPG SigmaCover (Amerlock) 400 has been specifically manufactured as a professional coating. With its unique formula, it is highly suitable for use on bridges, tank exteriors, containers and oil tanks. It has also achieved London Underground approval. Additionally, PPG SigmaCover 400 is ideal for chemical acid and fuel bunds.
Application
PPG SigmaCover 400 should be applied by spray, brush or roller. It produces a high quality, self priming, semi gloss finish and is available in a range of RAL and BS colours. SigmaCover 400 has a theoretical coverage rate of 8.7 square metres per litre and has an approximate drying time of 6 hours (touch dry). This theoretical coverage is based on a smooth non porous surface. For surfaces such as new unpainted concrete, this figure could be reduced dramatically. We suggest a sample is carried out to determine actually coverage rate.
Surface and Environment
PPG SigmaCover 400 can be used in commercial, construction and industrial environments where chemical spillages, splashes and fumes from acids, alkalis, solvents and water can cause damage to the surface. PPG SigmaCover 400 works by protecting steel and concrete substrates from these examples of chemical and atmospheric attack. Because of it's high resistance to weathering, SigmaCover 400 is perfect for application to exterior bund linings, including, chemical, fuel or specially selected acid bunds. PPG SigmaCover 400 can be applied over mechanically cleaned steel and is also suitable for use on concrete or prepared damp surfaces.
