Abstract: The present invention provides compositions for water vapor permeable hydrophobic coating comprising a blend of (i) a primary polyolefin dispersion of one or more large particle size polyolefins having a melting point of at least 95° C., and an average particle size of from 1 to 5 microns, and containing a volatile base and a 14 to 40 carbon long chain linear carboxylic acid dispersing agent, and (ii) a film forming second dispersion of one or more polymers having an average particle size of from 0.1 to 1.0 microns chosen from one or more polyolefins having a melting point from 50 to 90 ° C. further containing an at least partially neutralized olefin containing dispersing agent, one or more alkyl celluloses which further contain a plasticizer having a boiling point of 250° C. or greater and containing an at least partially neutralized olefin containing dispersing agent, and one or more acrylic emulsion polymers having a Tg of from 0 to 60° C. wherein the particle size ratio of the primary polyolefin dispersion to the second dispersion ranges from 3:1 to 29:1.
