Rayson StaticGuard · Static-control flooring
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.
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.

| Surface preparation | Substrate must be sound, clean and free of oil, grease, laitance, loose material and bond-inhibiting contaminants. Prepare concrete mechanically (captive shot blasting, milling or diamond grinding); remove weak concrete, open blowholes and voids, and reinstate imperfections with a suitable Rayson repair product. Vacuum all dust. New concrete should be at least 28 days old. A conductive earthing layer and grounding points must be installed as part of the static-control system. |
|---|---|
| Mixing / dilution | 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 |
| Application method | Steel trowel, Notched rake, Squeegee and roller, Spike roller immediately after trowelling |
| 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 |
| Application conditions | Minimum substrate temperature 5 °C; substrate moisture content max 5%; minimum mixing temperature +10 °C; cure between +10 °C and +35 °C; prepared substrate pull-off strength above 1.5 N/mm². |
| Drying & curing | Full cure approximately 7 days; minimise heavy traffic for 72 hours after application |
| Recoat interval | Available from the Rayson technical team on request. |
| Film / thickness | Target dry film thickness in the order of 1.0–1.5 mm. |
| Pack sizes | Part A 16 kg / Part B 4 kg per set |
| Storage | Minimum 12 months at 5–30 °C in unopened original packaging; protect from direct sunlight. |
| Shelf life | Approximately 12 months unopened; sunlight exposure reduces shelf life. |
