Abstract

A building assembly can include a substrate and a water barrier coating film. The water barrier coating film can include a thermoplastic polymer and microporous particles, such as microporous glass beads. The water barrier coating film can provide a good protection towards liquid water but may allow water vapor flow from the substrate through the coating film. The water vapor permeability of the water barrier coating film can be at least 2 US perms as tested according to ASTM E96 (2014) at 21° C. and 50% average relative humidity.
