Abstract
A method of can be used to make a wood composite material. The method includes forming a panel having wood fibers and additives, sanding a main surface of the panel, applying a polymer to the sanded main surface of the panel, and curing the polymer by irradiating the main surface of the panel. After the curing, the main surface has a solid discontinuous composite including a mixture of the wood fibers and cured polymer micro-islands.

A method of making a wood composite material, the method comprising:
- forming a panel comprising wood fibers and additives;
- sanding a main surface of the panel;
- applying a polymer to the sanded main surface of the panel;
- and
- curing the polymer by irradiating the main surface of the panel, wherein, after curing, the main surface comprises a solid discontinuous composite including a mixture of the wood fibers and cured polymer micro-islands.
A method of making a wood composite material, the method comprising:
- forming an OSB panel comprising wood fibers and additives;
- sanding a main surface of the panel with a grit finish between 60 and 120;
- applying between 40 g/m2 and 120 g/m2 of a water-based UV polymer to the sanded main surface of the panel using a spray technology;
- heating the panel at a temperature between 50° C. and 80° C. to remove water from the polymer;
- and
- curing the polymer by irradiating the main surface of the panel with UV radiation, wherein, after curing, the main surface comprises a solid discontinuous composite including a mixture of the wood fibers and cured polymer micro-islands.
A method of making a wood composite material, the method comprising:
