Conductive and Antistatic (ESD) Floor Coating Systems

Conductive or antistatic?

Coatings are classified by electrical resistance (DIN EN 61340-4-1, 100 V):

• Conductive: 10⁴–10⁶ Ω. Production and storage of explosive and flammable materials, aircraft hangars, car plants, paint shops.
• Antistatic (static-dissipative, ESD): 10⁶–10⁹ Ω. Electrical and electronic component production, test laboratories, lithium-ion battery production.

Values can vary with temperature, humidity and the measuring equipment; the final value is confirmed by measurement on the cured floor.

Conductive flooring system

1. Primer and earthing: the concrete is primed and copper strips are laid and connected to the building's earthing line.
2. Conductive primer: solvent-free DEMCO EPOX 195 PR/CONDUCTIVE (≤ 10⁴ Ω; 0.200–0.300 kg/m² per coat) or water-based DEMCO EPOX 181 PR CONDUCTIVE / WB (10³–10⁵ Ω).
3. Conductive or antistatic main coat: conductive epoxy DEMCO EPOX 2150 SELF/CONDUCTIVE, chemical-resistant conductive DEMCO EPOX 1901 SELF CONDUCTIVE/C, antistatic epoxy DEMCO EPOX 2100 SELF/ESD, elastic antistatic polyurethane DEMCO PUR 3150 SELF-ESD or antistatic PU concrete DEMCO PUR 303 CONCRETE NANO ESD/WB.
4. Topcoat and maintenance: textured anti-slip DEMCO EPOX 2160 TİX ESD; DEMCO EPOX 2155 TOP COAT / CONDUCTIVE for repair and maintenance of conductive floors.

Conductive coatings for steel and machinery

On metal surfaces, conductive epoxy primer DEMCO EPOX 2485 STEEL – CONDUCTIVE and conductive polyurethane topcoat DEMCO PUR 4150 TOP COAT UV/S – CONDUCTIVE prevent electrostatic charging; both have a surface resistance of 10⁴–10⁶ Ω and are designed for special machinery intended for ATEX applications. DEMCO PUR 4100 TOP COAT UVS ESD is the UV-stable topcoat in the antistatic range (10⁶–10⁹ Ω).
