Claims16
A decorative surface covering comprising a substrate having a top surface and a top-layer covering the top surface of said substrate, said top-layer comprising:
- 40 to 80% by weight of a thermally cured binder (i) comprising a polymer selected from the group consisting of epoxy resin, epoxy ester resin, vinyl ester resin, polyester, alkyd resin, polyamide, polyesteramide, polyurethane, polyether, (meth)acrylate (co)polymer, vinyl (co)polymer, aminoplast resin and mixtures thereof;
- 0.5 to 25% by weight of one or more types of micro-scale particle(s) (ii) with a volume median particle diameter (D50) comprised between 1 and 50 μm as obtained from laser light scattering measurements according to ISO 13320;
- and
- 0.1 to 20% by weight of one or more compounds (iii) selected from the group consisting of silicones, fluorocarbons, fluorinated silicones, olefin (co)polymers, natural waxes and synthetic waxes;
- wherein said decorative surface covering having a Slip Resistance, according to DIN 51130, corresponding to Slip Resistance Class equal to or superior to R9 and a Scuff Resistance of 8 or higher as assessed in a friction test apparatus with an Astral Rubber tool, with a thickness of 5 mm and a width of 0.8 mm, moving 1, 1, 2, 4 and 6 times with a loading of 3, 4, 5, 7 and 9 kg respectively over a 25 cm distance of a test panel at a speed of 0.40 m/s.
