Rayson StaticGuard CX90 is a two-component, solvent-free conductive epoxy flooring that gives ESD-protected areas a self-smoothing, permanently conductive, chemically resistant wearing surface.
Best for electronics production, data centres and other ESD-protected areas that need a grounded, seamless floor with high mechanical strength.
StaticGuard CX90 is the static-control floor in the Rayson range. The solvent-free, 100%-solids epoxy self-smooths into a seamless surface whose conductivity is built into the cured matrix — not a surface treatment that wears away. Measured electrostatic behaviour falls in the 10⁴–10⁶ ohm range on average, placing floors in conductive ESD territory when installed and earthed correctly.
Mechanically it is a serious floor: tensile and flexural strength up to 40 N/mm² in quartz-filled testing, abrasion loss around 100 mg in standard Taber testing, and excellent impact and chemical resistance. Typical duties include electronics facilities, data centres, antistatic floors and walls, EMI/RFI-shielded rooms, pharmaceutical facilities, aerospace hangars and storage areas.
Film thickness is critical to performance: the system targets 1.0–1.5 mm, and applying in excess of the stated thickness reduces conductivity. Grounding points, earthing layout and post-cure resistance verification should be planned with the facility engineer from day one.
A finish is the top coat. It provides the final appearance, cleanability and resistance to traffic, chemicals or UV.
The figures below are a guide for planning. Site conditions and workmanship affect results — confirm the details for your project with our technical team.
| Coverage | Minimum 2.25 kg binder per m² per coat at approximately 1.5 mm (optionally +0.25 kg quartz sand); approximately 5–8 m²/L at 75 µm DFT for thin coats; maximum ~2.5 kg/m² binder plus filler at 1.5 mm |
|---|---|
| Mixing | Two pre-weighed parts, mix ratio 4:1 (A:B) by weight; mix mechanically for at least 2–3 minutes; pot life up to 25 minutes at 28 °C |
| Drying & curing | Full cure approximately 7 days; minimise heavy traffic for 72 hours after application |
| Pack sizes | Part A 16 kg / Part B 4 kg per set |
Its average electrostatic behaviour is in the 10⁴–10⁶ ohm range, which sits in conductive ESD territory. The reading achieved on site also depends on installation, earthing, cleaning and how the measurement is taken — always verify against your facility standard.
Conductivity depends on the conductive network through the coating. Applying thicker than specified increases resistance and can push the floor out of its target range.
Grounding points are installed as part of the system, connected to the building earth by the electrical contractor. Agree the earthing layout with the facility engineer before installation.
With documented resistance testing after full cure, using the measurement method your facility standard specifies. Rayson recommends retesting on a scheduled basis thereafter.
Use cleaners that do not leave insulating films — waxes and polymer polishes can raise surface resistance and defeat the static control.
Keep heavy traffic off for at least 72 hours and allow around 7 days for full cure before resistance verification. Confirm programme timings with our technical team.
