ESD flooring for electronics and data centres

Electronics assembly and data centres need a seamless floor that stays clean and carries equipment and trolleys: E300SL and SL20 self-levelling epoxy, or E100 and SupaFloor coatings. Where static must be controlled, specify an ESD system — Hychem 177ESD (dissipative) or 266ESD (conductive) — from the conductive and anti-static range.

What the floor has to handle

Static
resistance to ground within the ESD programme's limits
People
body voltage generated by walking, with ESD footwear
Traffic
trolleys, racks and foot traffic on a hard-wearing surface
Earthing
copper tape and earth points built into the system

FAQs about ESD flooring for electronics and data centres

Dissipative or conductive?

A dissipative floor (Hychem 177ESD: up to 10⁹ Ω to earth) protects sensitive electronics; a conductive floor (Hychem 266ESD: up to 10⁶ Ω) discharges static fastest, for explosion-risk areas.

Is the floor enough on its own?

No. IEC 61340-5-1 treats the floor as one part of an ESD programme with footwear, grounding and testing; IEC 61340-4-5 tests the floor, shoes and person together.

Is ESD the same as anti-static?

Anti-static is the everyday word; ESD (electrostatic discharge) flooring is the specified, tested version, with measured resistance values.
