Modelling biocide release from architectural coatings

摘要

Biocides are a necessary component of architectural coatings, extending their service lives by preventing microbial defacement. However, they have the potential to enter surface waters in runoff from building facades during driving rain events. Increased regulation necessitates a closer look at the release process, both for proper source input estimations for regulators, and product development insights for producers. The mature field of controlled release offers o vast information store of research that can be applied to this particular problem, with adjustments made for problem-specific conditions such as how wind driven rain leads to focade runoff.
