Abstract

A building panel including a carrier, and a surface layer arranged on the carrier, wherein the surface layer includes a mix of refined fibres and a resin, wherein the weight ratio of resin to refined fibres is higher than about 120%, wherein the surface layer is applied as a dry powder layer.

Claims (17)

1. A building panel comprising:

a carrier; and

a colorful or white, non-transparent surface layer arranged on the carrier, wherein the surface layer is formed from a mix comprising refined fibres, pigments and a resin, wherein the weight ratio of resin to refined fibres is higher than about 120%,

wherein the surface layer is a cured layer, wherein the surface layer is applied as a dry powder layer, and

wherein the surface layer possesses between 30-40% refined fibres by weight, and wherein the surface layer is 0.2-1.0 mm thick.

2. The building panel according to claim 1 , wherein the mix forming the surface layer further comprises wear resistant particles.

3. The building panel according to claim 1 , wherein the pigments in the mix forming the surface layer comprises inorganic pigments, organic pigments or a combination thereof.

4. The building panel according to claim 1 , wherein the carrier is a wood fibre based core.

5. The building panel according to claim 4 , wherein the surface layer is attached to the wood fibre based core to obtain a building panel, wherein the core comprises a major part of the panel.

6. The building panel according to claim 4 , wherein the building panel is a floor panel.

7. The building panel according to claim 4 , wherein the carrier is an HDF panel.

8. The building panel according to claim 1 , wherein the weight ratio of resin compared to refined fibres is in the range of about 120% to about 180%.

9. The building panel according to claim 4 , wherein a balancing layer is applied to a surface of the wood fibre based core that is opposite to the surface layer.

10. The building panel according to claim 1 , wherein a sublayer is arranged between the carrier and the surface layer.

11. The building panel according to claim 10 , wherein the sublayer comprises a mix of wood fibres and a resin.

12. The building panel according to claim 1 , wherein the surface layer is white.

13. The building panel according to claim 1 , wherein the surface layer is devoid of wear resistant particles.
