POLYOLEFIN DISPERSION COMPOSITIONS FOR MAKING HIGH VAPOR TRANSPORT HYDROPHOBIC COATINGS |
摘要 |
The present invention provides compositions for water vapor permeable hydrophobic coating comprising a blend of (i) a primary polyolefin dispersion of one 5 or more large particle size polyolefins having a melting point of at least 95 OC, 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 0 50 to 90 OC 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 OC 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 OC wherein the particle size ratio of the primary 5 polyolefin dispersion to the second dispersion ranges from 3:1 to 29:1. |
