Rayson UraForce SB65
Rayson UraForce SB65 is a two-component, solvent-based aliphatic polyurethane clear topcoat with excellent abrasion resistance, non-yellowing behaviour and outstanding weather durability for concrete, metal and stone.
ConcreteWalls TDS RY-TDS-702
Best for
Best for clear protective finishes over floors, walls and hard surfaces that must stay non-yellowing under weather and UV.
UraForce SB65 is the clear aliphatic polyurethane in the Rayson range, available in gloss, satin and matt. It seals and dustproofs concrete and hard mineral surfaces with a film that will not yellow, offering outstanding weather resistance and durability alongside excellent abrasion resistance and low dirt pick-up.
The cured film measures pencil hardness above H and gloss of 85 at 60° in the gloss grade, with good water repellence and chemical resistance in wear. It bonds to mechanically prepared concrete, metal, stone and limestone, and serves as a hygienic, washable finish for walls as well as floors.
Mixing is 4:1 by volume with a working pot life of about 2 hours. As a solvent-based product it requires ventilation during application; for occupied spaces the water-based UraForce WB60 clear coat is the alternative.

Typical systems
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
- Solvent-based — provide adequate ventilation; not for occupied areas without ventilation control
- Thin-film clear coat — substrate defects and colour show through
Not suitable for
- Occupied or unventilated areas during application — solvent-based
- Hiding substrate defects or colour — it is a clear coat
- Heavy-duty build-ups — it is a thin protective film, not a wearing screed
