Facade thermal insulation varnish paint coatings

Abstract

The pairwise correlation of the building physical properties of water-based polymer dispersions in the coordinates of the Künzel's diagram clearly demonstrates that, in terms of hygroscopic, all samples under study are within 0.05 kg/m2 h, which corresponds to the hygroscopic class W3 (low hygroscopic properties according to ISO 1062-1). In terms of vapor permeability class, all the coatings studied are close to V1 class (high water vapor diffusivity, ISO 1062-1).
