| Résumé : |
Research and development teams have a vast array of fillers, pigments and dispersing and wetting additives to choose from when developing new coatings. The authors aimed to simplify this process by creating a novel nano-additive that can be used as a universal stabilising component. The resulting additive and process technology provides a way of reducing development time and undesirable side effects. |
