| Résumé : |
Of the three main groups of microorganisms that can infect paints 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, whilst algae also detract from the product's aesthetic qualities as well as retaining high levels of moisture with resultant damage. Exterior surfaces can become infected with both types of organisms and broad-spectrum antifungal/antialgal biocides have been developed to prevent such growths. However, changing EU regulations 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.
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. |
