Abstract

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.
