The invention further concerns a composition suitable such treatment.
Claims17
Method for treating a surface of board produced by pressing fibers, strands, particles, wafers, or sheets of biological fibrous material together with a binding agent, comprising a step of contacting the surface of said board with an aqueous solution containing hydrogen peroxide.
Method for treating a surface of wood based board selected from the group consisting of particleboard, medium density fiber board (MDF), waferboard, oriented wafer board and oriented strand board (OSB), comprising a step of contacting the surface of said board with an aqueous solution containing from about 1 to about 50 wt % of hydrogen peroxide.
Method for treating a surface of board produced by pressing fibers, strands, particles, or wafers of biological fibrous material together with a binding agent, comprising a step of contacting the surface of said board with an aqueous solution containing hydrogen peroxide and at least one surfactant.
Aqueous solution suitable for treating the surface of board based on biological fibrous material comprising from about 1 to about 50 wt % of hydrogen peroxide, and a dispersion of from about 0.005 to about 10 wt % of at least one of solid silica or a solid metal oxide.
