Publication number: 20150159035Abstract: The present invention relates to dispersion-based paints or varnishes, more particularly for use as coating material (architectural paint), which have a low pigment volume concentration (PVC), lower than the critical pigment volume concentration (CPVC). The varnishes have high water vapour permeability and low water absorption. They are notable for good weathering resistance and resistance to wet abrasion, shade stability and chalking stability, and a variable, adjustable gloss.Type: ApplicationFiled: July 10, 2013Publication date: June 11, 2015Applicant: EVONIK DEGUSSA GMBHInventors: Jan Hendrik Schattka, Thomas Matten, Stephan Fengler, Wernfried Heilen, Florian Hermes, Herbert Jung
