Title: (EN) IMPROVED MICROPOROUS WATERPROOF AND MOISTURE VAPOR PERMEABLE STRUCTURES, PROCESSES OF MANUFACTURE AND USEFUL ARTICLES THEREOF
(FR) STRUCTURES MICROPOREUSES IMPERMEABLES A L'EAU MAIS PERMEABLES A LA VAPEUR D'EAU, PROCEDE DE FABRICATION CONNEXE ET ARTICLES FABRIQUES A PARTIR DE CES STRUCTURES
Abstract: front page image
(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.
