Lanxess develops formulation for algicides in paints and coatings

Lanxess, one of the world’s leading manufacturers of biocidal active ingredients and biocide formulations, has started using a new formulation method for algicides in paints. The method delivers added benefits for algicidal formulations.

Several tests showed that it reduced active ingredient leaching from paints caused by rain by more than 50% compared to conventional algicides. By improving leaching behaviour, the method extends the lifetime of façade coatings and can reduce the amount of active ingredient required. Researchers in the Material Protection Products (MPP) business unit of Lanxess have used ‘slow-release technology’ to develop the formulation that exhibits a far better active ingredient retention rate in the colour matrix than standard dry-film preservation products.

MPP presented its biocidal active ingredients and biocide formulations at last month’s European Coatings Show.
