Abstract

La presente invención consiste en un procedimiento para proporcionar hidrofobicidad a la madera o productos madereros mediante un tratamiento químico-enzimático. Dicho tratamiento consiste en la aplicación de enzimas oxidasas, preferentemente lacasas, y de un compuesto fenólico con un grupo hidrofóbico a la madera o a un producto maderero bajo unas condiciones ambientales determinadas. En dichas condiciones, el enzima promueve la unión del compuesto con grupo hidrofóbico a la madera o producto maderero confiriendo la propiedad del compuesto a la madera o producto maderero tratado. La unión de este modo es permanente ya que el compuesto hidrofóbico se une a la madera mediante enlaces químicos estables, evitando su arrastre en posteriores lavados. Este tratamiento permite dotar a la madera de una mayor resistencia a la humedad, lo cual mejora su aplicación, debido al incremento de su estabilidad dimensional y su durabilidad.
