Rayson UraForce · Polyurethane finishes
Rayson UraForce WB58 is a two-component, water-based aliphatic polyurethane dispersion topcoat, crosslinked with a PUR hardener, for abrasion-resistant coloured finishes on concrete, metal and mineral surfaces.
UraForce WB58 brings aliphatic polyurethane performance to water-based application. The pigmented polyurethane dispersion crosslinks with its PUR hardener into a film with excellent abrasion resistance, low dirt pick-up, good water repellence and pencil hardness above H — a working finish that dustproofs and protects the substrate.

| Surface preparation | New concrete at least 28 days old, moisture below 5%; remove laitance and loose material; mechanically prepare damaged concrete to exposed aggregate. On existing concrete, prefer mechanical preparation and industrial vacuuming; degrease with industrial detergent; substrate sufficiently dry at surface relative humidity of 75% or lower. |
|---|---|
| Mixing / dilution | Two pre-weighed parts, mix ratio 9:1 by weight; stir parts separately, combine and mix with a slow-speed drill and paddle for 1–2 minutes; pot life 1–2 hours |
| Application method | Short-bristled brush, Roller |
| Coverage | Available from the Rayson technical team on request. |
| Application conditions | Minimum substrate temperature 5 °C; minimum mixing temperature 10 °C; minimum curing temperature 5 °C; keep floor dew point within 3 °C of atmospheric temperature. |
| Drying & curing | Surface dry 6 hours at 25 °C |
| Recoat interval | Available from the Rayson technical team on request. |
| Film / thickness | Applied at approximately 100 µm wet film per coat. |
| Pack sizes | Part A 4 Lt or 18 Lt pail + Part B 1 Lt or 2 Lt pail |
