Abstract
Coated porous materials that exhibit air permeability and repellency to liquids as well as coated, nonporous breathable materials are described as suitable for making ileostomy vent filters, transdermal drug substrates, agricultural and medical apparel, as well as paint and chemical protective garments. The coating composition is applied as a curable composition containing cross-linkable melamine, polyol and fluorocarbon alcohol precursors. Hydrophilic coatings may be prepared by incorporating a polyvalent salt with the curable composition.
