Abstract
A process for achieving a wear resistant translucent surface on surface elements (1) which comprises a decorative upper layer (2) and a supporting core (5). A number of layers of UV- or electron-beam curing lacquer are applied on a decorative surface, through a process comprising the steps;i) Applying a base layer of lacquer to a surface weight of 5-50 g/m2.ii) Applying hard particles with an average particle size in the range 10-150 &mgr;m which are sprinkled to an amount of 1-40 g/m2 on the still wet lacquer.iii) Curing the applied layer of lacquer to a desired viscosity.iv) Applying a covering layer of lacquer to a surface weight of 5-150 g/m2.v) Curing the applied layer of lacquer to a desired viscosity.vi) Applying a topcoat layer of lacquer with an additive of 5-35% of hard particles with an average size in the range 50 nm-30 &mgr;m to a surface weight of 2-20 g/m2.vii) Curing the applied layers of lacquer to a desired final viscosity.
