1. Product description

Rayson UraForce WB52 is a two-component, water-based aliphatic urethane floor topcoat — low-VOC, low-odour and UV-resistant — that can be combined with broadcast aggregate for an anti-slip finish.

UraForce WB52 is the finish coat of the Rayson water-based floor system. The two-component aliphatic urethane cures to a high-strength film with excellent abrasion resistance, low dirt pick-up, pencil hardness above H and gloss of 85 at 60° in the gloss grade — while staying low-VOC and low-odour for occupied buildings.

2. Recommended uses

  • UV-resistant topcoat for concrete floors
  • Topcoat finishes on hard surfaces such as stone and limestone
  • Hygienic coatings for walls and floors
  • Anti-slip walkway and ramp systems with broadcast aggregate

3. Suitable substrates

  • Mechanically prepared concrete (minimum 28 days old, moisture content below 5%)
  • Mineral substrates
  • Stone and limestone
  • Walls and floors

4. Key properties

  • Low VOC and low odour — occupied-building friendly
  • Excellent abrasion and staining resistance (Class 5, preliminary testing)
  • Non-yellowing with 1,000 h QUV weathering performance (preliminary testing)
  • Fast trafficable time supports overnight programmes
  • UV stability
  • Abrasion resistance
  • Low odour
  • Anti-slip
  • Fast return to service
  • Hygiene / washdown
