Revêtements en bâtiment:Peinture en bâtimentIndex. décimale : 667.9 Revêtements et enduits Résumé : Changing labelling regulations require new ideas and the introduction of new blends of biocides. The author explores the strategies for decontamination. Of the three main groups of microorganims that can infect paints, plasters and similar surface coatings it is fungi and algae that are especially problematic after the material has been applied. Fungi cause surface disfigurement and actual degradation, while algae also detract from the product's aesthetic qualities as well as retaining high levels of moisture with resultant damaging effects. Exterior surfaces can become infected with both types of organisms and broad-spectrum antifungal or antialgal biocides have been developed to prevent such growths. However, changing legislation relating to the labelling of such biocides, pressure from environmental and consumer groups and revised regulations concerning insulation of buildings, have placed greater and greater demands on biocides and have created a need for new products with novel properties.

Revêtements antisalissures:Peinture antisalissuresIndex. décimale : 667.9 Revêtements et enduits 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.

Much of the pressure for change results from European legislation. However, the new formulations developed as a result of it are ideally suited to the harsh Sub-Continent climate. Active agents can be protected against UV degradation, alkaline attack and leaching and enable products with reduced toxicity, environmental impact and less tendency to cause discolouration as well as providing improved, cost effective performance.Note de contenu : - THE GROWTH OF MICROORGANISMS ON SURFACE COATINGS : Fungal and algal growth - Fungi and algae causing disfigurement and deterioration - Breakdown of surface coatings - The effects of fungal and algal growth
