Title (EN) VAPOR RETARDING BUILDING MATERIALS AND METHODS FOR MAKING THEM
(FR) MATÉRIAUX DE CONSTRUCTION À RETARDEMENT DE VAPEUR ET PROCÉDÉS POUR LEUR FABRICATION
Abstract:
(EN) The present disclosure relates generally to vapor retarding building materials and methods for making them. The present inventors have found simple and cost-efficient materials that have low water vapor permeability at low relative humidities and that can be provided as a coating on a building material substrate. Notably, in many embodiments, the materials can have high water vapor permeability at high relative humidities, in one embodiment, the disclosure provides vapor retarding articles comprising a building material substrate; and a polymeric coating layer coated on the building material substrate, the polymeric coating layer comprising an inorganic hydrophiiic particulate filler dispersed in a continuous organic phase comprising a hydrophobic polymer, wherein the content of the filler is from about 30% to about 85% by weight of the polymeric coating layer, the vapor retarding article configured to have a water vapor permeance of no more than about 1 Perm at 25% relative humidity.
(FR) La présente invention se rapporte généralement à des matériaux de construction à retardement de vapeur et à leurs procédés de fabrication. Les présents inventeurs ont découvert des matériaux simples et économiques qui ont une faible perméabilité à la vapeur d'eau à de faibles humidités relatives et qui peuvent être fournis sous la forme d'un revêtement sur un substrat de matériau de construction. En particulier, dans de nombreux modes de réalisation, les matériaux peuvent avoir une perméabilité à la vapeur d'eau élevée à des humidités relatives élevées, dans un mode de réalisation, l'invention concerne des articles retardateurs de vapeur comprenant un substrat de matériau de construction ; et une couche de revêtement polymère appliquée sur le substrat de matériau de construction, la couche de revêtement polymère comprenant une charge particulaire hydrophile inorganique dispersée dans une phase organique continue comprenant un polymère hydrophobe, la teneur en charge étant d'environ 30 % à environ 85 % en poids de la couche de revêtement polymère, l'article retardateur de vapeur étant conçu pour avoir une perméance à la vapeur d'eau inférieure ou égale à environ 1 Perm à 25 % d'humidité relative.
