[Microbial settlement of paint- and building-materials in the sphere of drinking-water. 6. Communication: Experimental examination of chlorcaoutchouc paints under working conditions and in laboratory tests (author's transl)].

Five different chlorcaoutchouc coating materials were microbiologically tested. All materials showed a visible microbial growth on the surface. The amount of slime decreased with the increase of age of the coat of paint. After a period of 1 to 1 1/2 years no visible microbial growth could be observed. The decrease of microbial growth on the coat of paint is independent on having been in contact with water or air before. One can say that the main compound of the coating material does not itself produce the visible microbial growth, but additions like volatile compounds.
