1. Product description

Rayson UraForce WB60 is a two-component, water-based aliphatic polyurethane dispersion clear coat, crosslinked with a solvent-free hardener, giving a non-yellowing, abrasion-resistant finish in gloss, satin or matt.

UraForce WB60 is the water-based clear coat of the UraForce family. The aliphatic polyurethane dispersion crosslinks with a solvent-free hardener into a non-yellowing film with excellent abrasion resistance, low dirt pick-up and good water repellence — pencil hardness above H and gloss of 85 at 60° in the gloss grade.

2. Recommended uses

UV-resistant clear sealing of concrete floors
Topcoat finishes on hard surfaces such as stone and limestone
Hygienic coatings for walls and floors
Non-yellowing protective finishes in occupied commercial interiors

3. Suitable substrates

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

4. Key properties

Low VOC, low odour — suited to occupied buildings
Non-yellowing aliphatic PU clear coat in gloss, satin or matt
Excellent abrasion resistance and low dirt pick-up
Solvent-free hardener system
UV stability
Abrasion resistance
Low odour
Hygiene / washdown

6. Technical data

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 approximately 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	18 kg pail (base) + 2 kg pail (hardener)
Storage	Store under cover in dry conditions, protected from temperature extremes.
Shelf life	Approximately 12 months for Part A; 6–12 months for Part B, unopened.

7. Application workflow

Figure 2 — Application workflow. Each stage is a hold point: confirm the previous stage is complete and within specification before proceeding.

8. Recommended system

Clear low-odour floor seal

Prepare the substrate mechanically and vacuum clean
Apply minimum 2 coats of Rayson UraForce WB60, stripe-coating edges by brush

9. Limitations

Minimum substrate temperature 5 °C; minimum mixing temperature 10 °C; minimum curing temperature 5 °C
Mixed material must be used within its pot life; cures faster in hot weather and in large batches
Hardener has a shorter shelf life than the base — store sealed and dry
Clear coat — substrate appearance and defects show through

10. Health & safety

Low-odour water-based product. Wear gloves and eye protection; ensure reasonable ventilation. Avoid skin and eye contact. Keep out of reach of children. Consult the Safety Data Sheet (in preparation) before use.
