Abstract
Un produit de bois composite selon un mode de réalisation en particulier de la présente technologie comprend un substrat composite et un scellant placé dans une partie de surface du substrat. Le substrat comprend du bois et un adhésif. Le scellant comprend des molécules photoréactives présentes dans la partie de surface du substrat en concentration moyenne de plus de 1 000 parties par million. En réponse à une exposition de 120 jours, à une distance de séparation de 7 po par rapport à une lampe ultraviolette à sortie de rayonnement ultraviolet A (315-400 nm) de 13,6 W et à sortie de rayonnement ultraviolet B (280-315 nm) de 3,0 W, une valeur b* CIE 1976 du substrat diminuant dune première quantité, une valeur b* CIE 1976 du scellant augmentant dune deuxième quantité et une valeur b* CIE 1976 du produit de bois en général diminuant dune quantité plus petite que la première, augmentant dune quantité plus petite que la deuxième ou demeurant inchangée.
