Abstract
Disclosed is a surface covering including: a wood-based substrate; a surface coating layer, the surface coating layer being obtained by the irradiation of a radiation-curable coating agent with UV light having a wavelength included from 120 nm to 230 nm; and a filler coating layer, the filler coating layer being located between the wood-based substrate and the surface coating layer. Also disclosed is a method for the manufacture of such a surface covering.
Claims13
A surface covering comprising:
- a wood-based substrate comprising a bottom layer, a core layer and an upper layer applied on the core layer, the upper layer being made of wood or derived from wood,
- a surface coating layer, said surface coating layer being obtained by the irradiation of a radiation-curable coating agent with UV light having a wavelength comprised from 120 nm to 230 nm, followed by the curing of said coating by irradiation with UV light having a wavelength comprised from 280 nm to 420 nm, and
- a filler coating layer, said filler coating layer being located between the wood-based substrate and the surface coating layer,
- wherein said filler coating layer is obtained by actinic radiation of oligomers and/or polymers selected from the group consisting of (meth)acrylate copolymers, polyether (meth)acrylates, polyester (meth)acrylates, epoxy (meth)acrylates, urethane (meth)acrylates, amino (meth)acrylates, melamine (meth)acrylates, silicone (meth)acrylates and phosphazene (meth)acrylates and has a thickness from 5 μm to 40 μm.
