摘要:
The present invention proposes a surface coating composition for formation of films having high water vapor permeability, comprising at least %5 by weight of acicular extender having an aspect ratio higher than 4:1, with respect to the total weight of the surface coating composition. The present invention further proposes a method for preparation of a surface coating composition for formation of films having high water vapor permeability, said method comprising the sequential steps of: loading water, surfactant, a first portion of thickener and a pH modifier into a disperser, and applying a low-shear mixing thereon for at least three minutes, thus obtaining a first mixture; adding dispersant and one or more acicular extender having an aspect ratio higher than 4:1 onto said first mixture, and applying a high-shear mixing thereon for 10 to 15 minutes, thus obtaining a grind; and adding additives onto said grind, and applying a low-shear mixing thereon for at least three minutes; wherein said additives comprisin
