ECS 2021: Protecting your walls – novel solutions for interior & exterior wall paints
Wall paints are a very important application within Architectural Coatings - and renewing them is quite laborious. Optimizing the resistance to damage and wear leads to more economical and sustainable paint formulations, as it makes renovation of e.g. façades with the costly installation of scaffolding redundant. One particular headache for freshly painted façades can be the formation of so called snail trails causing an uneven appearance when there is high humidity or rain. New specialty fillers help to prevent these problems and allow to formulate very long-lasting beautiful films when formulated e.g. with optimized hydrophobing agents. For interior coatings, innovative fillers also play a major role for optimization of mechanical resistance e.g., burnish phenomena - in addition, the use of suitable surface-active agents facilitates the optimization of scuff and chemical resistance. Studies of film formation help to understand and optimize both interior and exterior formulations.

Navigating the Complexities of Wetting in Ink and Coating Formulations
The ability to effectively wet challenging surfaces has emerged as a significant hurdle in the formulation of inks and coatings. With the ongoing advancements in packaging materials, including low-density polyethylene, oriented polypropylene, metallic films, and aluminum foil, formulators face increasing complexities. Furthermore, evolving regulatory standards necessitate that products not only perform optimally during printing but also comply with consumer safety regulations. Additionally, issues related to hydrolytic stability of surfactants have led to variations in ink wetting properties over the product's shelf life.
In this presentation, an expert from Evonik had discussed the relationship between surface tension and substrate wetting, as well as the distinct roles of dynamic and static surface tension in both water-based and energy-cured systems. While a one-size-fits-all solution is not feasible, the diverse range of products offered by Evonik Coating Additives provides effective strategies to tackle these wetting challenges.
