Abstract:
(EN) A process for manufacturing the composition coating may include selecting a wood or masonry material substrate and utilizing a sol-gel comprising a silane or silane derivative and metal oxide precursor to coat the substrate. The process may utilize an all solution process or controlled environment for manufacturing a composition coating that prevent wetting and/or staining of a substrate,. The composition coatings for treating wood or masonry materials improves weather-resistance, microbial resistance, stain-resistance and fungal-resistance of the materials. The reduced permeability of the resulting masonry materials can also delay or inhibit degradation caused by permeation of ions such as chlorides and sulfates. In addition, a stain comprising the composite solution and pigments may impart additional property to wood or masonry materials whilst retaining or improving the original appearance, particularly for the visibility and contrast of the wood grain as seen after the application of the coating.
(FR) La présente invention concerne un procédé de fabrication de la composition de revêtement pouvant consister à sélectionner un substrat de bois ou de matériau de maçonnerie et utiliser un sol-gel comprenant un silane ou à un dérivé de silane, et un précurseur d'oxyde métallique pour revêtir le substrat. Le procédé peut utiliser un procédé tout en solution ou un environnement contrôlé pour fabriquer une composition de revêtement qui empêche le mouillage et/ou la coloration d'un substrat. La composition de revêtement pour le traitement du bois ou de matériaux de maçonnerie améliore la résistance aux intempéries, la résistance microbienne, la résistance aux taches et la résistance aux champignons des matériaux. La perméabilité réduite des matériaux de maçonnerie obtenus peut également retarder ou inhiber la dégradation provoquée par la perméation d'ions, comme les chlorures et les sulfates. En outre, une teinture comprenant la solution composite et des pigments peut conférer une propriété supplémentaire au bois ou aux matériaux de maçonnerie tout en conservant ou en améliorant l'aspect original, en particulier pour la visibilité et le contraste des grains de bois tels qu'observés après l'application du revêtement.
