Résumé : |
Coatings provide both protection and aesthetic appeal. Just a thin layer of paint can extend the useful life of everyday objects, avoiding the environmental burden that would corne with an early replacement. Assessing the sustainability of coatings over the entire product life cycle better captures the impact of coatings performance in a given application. Highly treated grades of TiO2 increase scattering efficiency, reduce the required paint volume and offer a lower carbon footprint. |
