Abstract
In this study it was tested, which mechanism for the transport of biocides in polymeric renders is more relevant: (1) evaporative transports (meaning there is a flow of water through the material due to evaporation on the surface), which transports also the biocides to the surface, (2) transport through the polymer and (3) transport through water filled pores. It turned out that under the experimental conditions evaporative transport was not relevant, while transport through soaked (constantly wetted) renders was considerably faster than by other means. Additionally it turned out that also the equilibria were influenced by the water content. Differences in equilibria can be up to factor 10 between constantly wetted (soaked) and un-wetted materials. The two tested materials (one silicone and one acrylate render) had significantly different leaching behavior concerning equilibria and dynamics of mass flows, but for both the pre-wetted materials leached most.
