Study on the painting system on the pre-cast concrete panel

Abstract

This paper reports about the painting system on the pre-cast concrete panel. We evaluated micro-crack resistance and anti-blowning of the paint system and examined four paint systems. In exposure test, it caused micro-crack of some ceramic paint. And the result of the cyclic bending test explained that the paint system did not have micro-crack resistance. It caused blowning of some fluoride resin paint. But this paint system had high water holding capacity and vapor peamiability. So anti-blowning property was not related to vapor permeability and water holding capacity.
