Simply to the ESD floor

ESD protection zones, server rooms, battery rooms, or storage for flammable materials – the new electrically conductive sealing system StoFloor ESD WL 213 (StoCretec) is versatile. The semi-matte water-based lacquer StoPox WL 213 is suitable for old and new electrically conductive epoxy resin coatings. Mineral substrates can even be retrofitted to become ESD floors.

StoFloor ESD WL 213 is a versatile and easy-to-apply sealing system. It works not only on solvent-free, conductive epoxy resin coatings but also on mineral substrates such as concrete, cement screed, magnesia screed, or calcium sulfate screed. It does not require an additional conductive layer; a two-coat application of the floor coating with an intermediate grounding (StoDivers LS grounding set and StoDivers LB 100 grounding tape) is sufficient. Even non-conductive standard floors can be converted into ESD floors this way. This makes StoFloor ESD WL 213 also ideal for renovation.

The semi-matte surface is easy to clean, and its high lightfastness prevents yellowing or fading. Additionally, the surface is abrasion-resistant, chemically resistant, and resistant to plasticizers. The low-emission lacquer is free of silicones, nonylphenol, and benzyl alcohol. It can be applied easily and quickly without special expertise – manually or with an airless spray device.

ESD properties:

- System resistance < 10^9 Ohms according to DIN EN 61340-5-1:2017-07
