Title (EN) IMPROVED MICROPOROUS WATERPROOF AND MOISTURE VAPOR PERMEABLE STRUCTURES, PROCESSES OF MANUFACTURE AND USEFUL ARTICLES THEREOF
(FR) STRUCTURES MICROPOREUSES ETANCHES A L'EAU ET PERMEABLES A LA VAPEUR, LEURS PROCEDES DE FABRICATION ET ARTICLES UTILES
Abstract:
(EN) Microporous waterproof and moisture vapor permeable products are described which are formed from a matrix having an internal microstructure which is coated with a hydrophobic material. A process is described including the steps of (1) applying to the surface of the matrix a liquid hydrophobic material, (2) allowing the liquid to penetrate into the microstructure and then (3) drying, vulcanizing or curing the product.
(FR) Produits microporeux étanches à l'eau et perméables à la vapeur formés à partir d'une matrice présentant une microstructure interne revêtue d'une matière hydrophobe. L'invention concerne un procédé comprenant les étapes consistant (1) à appliquer à la surface de la matrice une matière hydrophobe liquide, (2) à laisser le liquide pénétrer dans la microstructure et ensuite (3) à sécher, vulcaniser ou polymériser le produit.
