Conductive Adhesive for ESD Flooring

The adhesive conducts charge from the vinyl surface down to the copper tape and building earth — a standard adhesive would break the path.

The adhesive's own resistance is a material property: tested to JC/T 550-2019 (antistatic grade) with a requirement of ≤ 3 × 10⁵ Ω. Resistance measured on a finished floor is a system value - determined by the sheet, the adhesive, the earthing network, the substrate and the measurement method - and must be agreed in writing against the project specification before installation.

A 20 L (20 kg) pail covers roughly 80-90 m² at a consumption of 220 - 250 g/m².

Yes - the film has to stay continuous. The adhesive conducts through overlapping conductive fibres; a roller picks those fibres up and pushes them towards the edge of the work area, so the network breaks up and local high-resistance points appear. A notched trowel lays an even film across the whole area and keeps the designed thickness once the ribs collapse. Curing problems can be corrected afterwards - fibre loss cannot.

No - and no single material can, which is why we do not publish a finished-floor figure. Resistance on a completed floor is a system value: it depends on the sheet, the adhesive, the earthing network, the substrate and the measurement method. What we do instead is agree the acceptance limit, the test method and the measuring conditions with you in writing before installation. The relevant documents are IEC 61340-4-1 (test method for the resistive properties of floors) and IEC 61340-5-1 (system requirements - the floor of an ESD-protected area is specified below 1 x 10^9 ohm).
