Résumé : |
Fungal and algal growth on both interior and exterior coatings has been recognised as a serious problem for many years and biocidal additives have been developed to deal with such growths. However, when such products are considered in detail it will be seen that only a small number of active agents are used in such formulations. These are now under pressure as a result of changed industry needs, environmental and consumer demands and the activities of regulatory authorities, especially those in Europe. As a result, particularly of the implementation of the Biocidal Products Directive (BPD) and the Adaptations to Technical Progress (ATP) of the Dangerous Substances Directive (DSD), active agents used in the past are now being either discontinued or much more strongly restricted, creating a need for new products will novel properties. Although such demands represent a significant challenge to the biocide manufacturer it has been possible to meet these requirements. |
