Johor is now one of Asia-Pacific’s largest data-centre markets, and every one of those buildings has plant rooms, battery rooms and build areas that need a grounded floor the consultant can measure. Rayson StaticGuard CX90 is a conductive epoxy designed to that target, with the earthing layout and the verification planned in from day one.
| Item | StaticGuard CX90 | Note |
|---|---|---|
| Electrostatic behaviour | 10⁴ to 10⁶ ohm range on average | Conductive band; depends on installation, earthing, cleaning and the measurement method |
| Programme standards | IEC 61340-5-1, ANSI/ESD S20.20 | The floor is one element of the programme; footwear and procedures are the rest |
| Test methods | ANSI/ESD STM7.1, IEC 61340-4-1 | Resistance to ground and point-to-point, measured after cure and recorded |
| System thickness | 1.0 to 1.5 mm | Thicker application raises resistance; wet-film checked during installation |
| Binder | Solvent-free, 100% solids epoxy, self-smoothing | Conductivity in the cured matrix, not a surface treatment |
| Mechanical | Tensile and flexural strength up to 40 N/mm² in quartz-filled testing; Taber abrasion loss around 100 mg | Forklift and pallet-truck traffic in stores and loading areas |
| Earthing | Grounding points in the system, connected to building earth | Layout agreed with the facility engineer and the M&E contractor before installation |
Figures are from the StaticGuard CX90 technical data sheet. Ask for the data sheet and the test method with your enquiry; both go into the submission.
On a data-centre job the floor is specified by the consultant, bought by the M&E or main contractor and installed under a programme that does not wait. Rayson gives the contractor a data sheet, a method and an applicator; gives the consultant the standards and the test record; and gives the operator a floor that measures the same in year three as on handover day.
The slab must be dry, sound and ground before the primer; the earthing layout must be fixed before the first coat. We say this early because it is where ESD floors go wrong.

System build-up, thickness, grounding layout and the test method, with the data sheet, within one working day.
The authorised applicator for your area or your crew installs to the method; resistance is measured after cure and recorded for the consultant.
Conductive floors measure roughly 10⁴ to 10⁶ ohm to ground; dissipative floors 10⁶ to 10⁹ ohm. ANSI/ESD S20.20 and IEC 61340-5-1 set the system target (floor plus footwear) at under 10⁹ ohm with the person’s body voltage limited; many electronics and data-centre specifications ask for a conductive floor so the system has margin. StaticGuard CX90 measures in the 10⁴ to 10⁶ ohm range on average when installed and earthed correctly. Confirm the target with the consultant before the floor is specified.
No. S20.20 and IEC 61340-5-1 describe an ESD control programme: grounded work surfaces, personnel grounding through footwear or wrist straps, handling procedures, training and periodic verification. The floor is one element. Rayson supplies a floor designed to a stated electrical target with published data, and the installed floor is measured and documented; compliance is assessed across the programme.
Data halls usually have raised access floors with their own conductive tiles; under them the slab gets a sealer, conductive where the design asks for a grounded path. The epoxy ESD floor is for the rooms around the hall: electrical and switch rooms, UPS and battery rooms, plant rooms, corridors, staging and build rooms, loading and unpacking areas where equipment is handled out of its packaging.
Grounding points, usually copper tape or earthing strips at agreed spacing, are laid into the system and connected to the building earth by the electrical contractor. After cure, resistance to ground and point-to-point resistance are measured to ANSI/ESD STM7.1 or IEC 61340-4-1 and recorded for the consultant. The earthing layout is agreed with the facility engineer before installation.
The conductivity of CX90 is built into the cured matrix, not applied as a surface treatment that wears away. The system targets 1.0 to 1.5 mm; applying thicker than specified raises resistance and can push the floor out of its target range. The applicator checks wet-film thickness as the floor goes down.
Johor, Kuala Lumpur and Penang, through authorised applicators introduced by Rayson: in Johor, the Sedenak, Nusajaya and Iskandar Puteri data-centre clusters, Kulai, Senai and Pasir Gudang; in Penang, the electronics plants of Bayan Lepas, Batu Kawan and Prai; and sites in Kuala Lumpur and the Klang Valley. For plants elsewhere, such as Kulim, Rayson supplies the material and the method to the contractor’s own crew. The applicator quotes, invoices and warrants the workmanship; Rayson warrants the material.
Tell us what the surface is, where it is and what it has to withstand. Rayson replies with a system recommendation; for installation, the applicator for your area in Johor, Kuala Lumpur or Penang is introduced to quote the job.
Malaysia launch: 1 March 2027. Enquiries are welcome now; supply, site assessment and installation timing are confirmed for each project.
