Abstract
A powder mix layer for a building panel and a method for producing a building panel with a decorative surface produced from a powder mix layer with a controlled loss on cure. A method of producing a building panel including the steps of applying a powder mix layer on a substrate, and applying heat and pressure to the powder mix layer and curing the powder mix layer having a loss on cure in the range of about 2 to about 7 wt-%, and thereby obtaining a layer formed by the powder mix layer.

A method of producing a building panel comprising the steps of:
- applying a powder mix layer on a substrate, the powder mix layer comprising a fiber and a binder;
- and
- applying heat and pressure to the powder mix layer having a free moisture content in the range of about 0.6 to about 6.1 wt-%, and thereby obtaining a layer of the building panel formed by the powder mix layer.
A method of producing a building panel comprising the steps of:
- applying a powder mix layer on a substrate, the powder mix layer comprising a fiber and a binder;
- adjusting a free moisture content of the powder mix layer by a step of applying a stabilization fluid, or a step of drying, or a combination thereof, such that the powder mix layer obtains the free moisture content in a range of about 0.6 to about 6.1 wt-%;
- and
- applying heat and pressure to the powder mix layer having the free moisture content in the range of about 0.6 to about 6.1 wt-%, and thereby obtaining a layer of the building panel formed by the powder mix layer.
A powder mix layer for producing a building panel, wherein the powder mix layer comprises a fiber and a binder and has a free moisture content in the range of about 0.6 to about 6.1 wt-%.
