Rayson formulates and specifies StaticGuard CX90, a conductive ESD epoxy system, in Singapore and has it made to that specification by its production partners; every batch is tested and released in Singapore. From substrate assessment and grounding coordination to post-installation resistance verification, every layer creates one measurable path to earth.
It creates a controlled path for electrostatic charge through substrate preparation, primer, conductive layers, grounding points and a conductive wearing coat. Set the conductive or static-dissipative target from the facility ESD programme first, then verify the installed floor on site.
Read the StaticGuard CX90 technical dataThis is not a visual choice. The facility ESD programme, sensitive components, personnel contact, footwear and verification method decide the target; the floor system and earthing path follow.
For controlled areas whose specification calls for a lower resistance range. The published StaticGuard CX90 data reports average electrostatic behaviour of 10⁴–10⁶ Ω when installed and earthed correctly.

Read the ESD standards guideBoth classes drain charge to earth. They differ in how fast, and in how much resistance stays in the path. Conductive flooring occupies the lower resistance band and drains charge fastest; static-dissipative flooring sits in a higher band and drains it in a more controlled way. Neither is universally better, and neither is visible — two floors in the same colour can belong to different classes, and the same product can measure differently in two buildings.
Resistance to ground: the electrical resistance between the walking surface and the facility earth. A class name is shorthand for that one measured value. It is a property of the installed system — material, thickness, earthing layer, grounding connections and the concrete underneath — not a property of a pail of resin.
A lower target demands a continuous conductive network, tighter thickness control and a denser earthing layout. A higher, more controlled target changes the primer route and the acceptance criteria. Fix the target first: the build-up, the earthing plan and the test method all follow from it, and moving a finished floor between bands usually means removing it.
The facility ESD coordinator sets the band from the ESD control programme and the sensitivity of what is handled. The manufacturer states what the system is designed to achieve. The applicator installs it. The measured floor proves it. Rayson publishes the StaticGuard CX90 data so the first of those four is checkable before anyone orders material.
Rayson does not decide your band. Bring the requirement out of your facility ESD control programme, then read how a stated band becomes a site measurement in the ESD flooring standards guide.
Quotations, tenders and product pages use these terms almost interchangeably, and only some of them carry an electrical commitment. Read every one of them as a question: which band, and how will it be measured?
None of these names replaces the two things that matter: the band the system is designed for, and the measured record from the finished floor. Read the ESD flooring standards guide, or go straight to the StaticGuard CX90 TDS (PDF).
Define the requirement around people, sensitive components or the electrical path before discussing a coating.
Across workstations, routes and transitions, people, footwear and flooring need to support the facility’s defined ESD-control requirement.
Assembly, testing and packing areas need a traceable static-control path—not simply a clean-looking floor.
Copper grounding points, conductive layers and the building earth need coordination before installation. A floor can look right and still measure wrong.
The ESD programme standards most audits reference — the ANSI/ESD S20.20 family and its IEC 61340 counterparts — describe how a facility controls static, not which coating to buy. They define grounded work surfaces, personnel grounding, handling procedures, training and verification. The floor is one element inside that: its job is to provide a controlled electrical path from a standing person to earth, working together with ESD footwear.
So no supplier — Rayson included — can sell compliance in a pail. What a manufacturer can honestly offer is a system designed to a stated electrical target, published data you can read before ordering, and an installed floor that is measured and documented. The rest of the programme belongs to the facility. See electronics facility flooring for how these elements sit together on a real production floor.
The target resistance range defines the system, grounding layout and verification method. Product selection follows that target.
Read the StaticGuard CX90 technical dataThe system primer and grounding layout must be confirmed for the project by the Rayson technical team, facility engineer and relevant electrical personnel. Read the ESD flooring standards guide to understand how project requirements become site verification.
A conductive coat that is not bonded to the facility earth is an expensive grey floor. The path runs from the walking surface, through the conductive network in the build-up, into copper grounding strips, out to earth points, and back to the building earth. Every joint in that chain is installation work — and every joint is a place a floor can measure wrong while looking perfect.
The published StaticGuard CX90 build-up places the conductive earthing layer and grounding points directly beneath the wearing coat, over a conductive primer on prepared concrete. Rayson’s technical team confirms the primer route and earthing layout for the project with the facility engineer and the electrical contractor. Read the StaticGuard CX90 TDS (PDF).
This is the published build-up and the published numbers. Read the technical data sheet while you are writing the specification — not after the material arrives on site.
Curing between +10 °C and +35 °C, minimum substrate temperature 5 °C. The full published data — surface preparation, application conditions, storage and the complete build-up — is in the StaticGuard CX90 TDS (PDF), and material quantities can be estimated with the coverage calculator. Rayson manufactures the material; the installed price is set by the applicator.
The completed floor must be measured and documented using the method agreed for the project. The published TDS is the starting point; site verification is the handover evidence.
Confirm the target, test method and measurement positions.
Test the completed floor after the appropriate cure.
Record the result for handover and future maintenance.
Colour does not prove performance. A product name does not prove performance. A number recorded at a known position, on a known date, with a calibrated instrument is the only thing that does. This is the sequence a Rayson ESD floor should be handed over on.
The published StaticGuard CX90 data is explicit that measured readings are affected by:
So compare like with like. A reading that moves between two visits may be telling you about the meter, the footwear or last night’s cleaning chemistry rather than about the floor. Fix the method first, then trust the trend. Read the StaticGuard CX90 TDS (PDF).
They were correct materials dropped into an incomplete system. These are the ways a floor that looks right ends up measuring wrong.
None of these is solved by changing coating. They are prevented by grounding coordination at design stage, thickness control during installation, and a measured record at handover. For adjacent general-production zones see LevelShield SL120; for static-control areas see StaticGuard CX90.

Anyone can call a floor “ESD”. These questions separate a specified electrical system from a grey coating with a claim attached. Rayson’s answers are on this page and in the published data — ask any supplier for theirs in writing.

Open the libraryESD flooring is a conductive or static-dissipative floor system that gives static charge a controlled path to earth. The floor works as part of a complete ESD programme that includes the specified target, grounding arrangement, footwear and post-installation verification.
Yes. A conductive wearing coat alone does not establish a verified path to earth. The earthing layer, copper grounding points and connection to building earth must be agreed for the project with the relevant facility and electrical personnel.
They are different electrical-performance classes. The correct class and target range come from the facility ESD programme or project specification. Select the target first, then design the complete flooring and grounding system around it.
The completed floor is measured after the appropriate cure using the project-agreed method, including resistance-to-ground and/or point-to-point testing as required. Readings should be documented for handover and future maintenance.
The existing coating and substrate must first be assessed. A conductive system requires its own controlled build-up and grounding arrangement, so local appearance alone cannot confirm suitability. Send the current floor details and ESD target for review.
Use cleaning products that do not leave an insulating film. Waxes and some polymer polishes can change surface behaviour. Repair damage promptly and schedule retesting in line with the facility ESD programme.
The published Rayson StaticGuard CX90 data reports average electrostatic behaviour in the 10⁴–10⁶ ohm range when the system is installed and earthed correctly. Final acceptance must use the target and test method set by the facility ESD programme.
No. An ESD floor is one controlled element within the wider ESD programme. Footwear, personnel practices, equipment grounding, test method and documented results also need to meet the facility’s applicable requirements.
“Anti-static” is used loosely for anything that reduces static build-up. ESD flooring is specified by measured resistance to ground and a defined class — conductive or static-dissipative. A floor described only as anti-static, with no stated electrical target and no test method, is a marketing description rather than a specification. Ask which band it is designed for, and how the installed floor will be verified.
Test points are fixed on the floor plan across the whole area before installation, and the method, instrument and acceptance criteria are agreed at the same time. After full cure the surface is cleaned and each marked point is measured from the walking surface to the facility earth with a calibrated meter, with point-to-point readings added where the project calls for them. Every reading is recorded with its position, instrument, date and ambient conditions, then issued with the handover documents.
No. A thin conductive paint and a conductive epoxy flooring system are not interchangeable. StaticGuard CX90 is a two-component, solvent-free, self-smoothing epoxy applied at a target 1.0–1.5 mm, with conductivity built into the cured matrix rather than applied as a surface treatment, and it works over a conductive primer with an earthing layer and grounding points. Any coating installed without that earthing system has no verified path to earth, whatever it is called.
No. ANSI/ESD S20.20 and its IEC 61340 counterparts define an ESD control programme — grounded work surfaces, personnel grounding through footwear or wrist straps, handling procedures, training and verification. The floor is one element of it. A manufacturer can supply a system designed to a stated electrical target with published data, and the installed floor can be measured and documented; compliance is assessed across the whole programme, not on a product.
Ask in writing for: the electrical target the system is designed to achieve and where it is published; the technical data sheet before ordering; the complete build-up including the conductive primer and earthing layer; who bonds the grounding back to the building earth; the test method, test-point plan and acceptance criteria; the specified thickness and how it is controlled on site; compatible cleaning products; and the re-test recommendation.
The published target dry film thickness is 1.0–1.5 mm. Conductivity depends on the conductive network through the coating body, so applying above the stated thickness increases resistance and can push the floor out of its target band. On a conductive floor, thickness control is a performance requirement rather than a finish tolerance.
