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.

Paper: Fine-tuning coating surface control through the use of modified siloxanes

Siloxane-based additives are critical tools in coating applications because their structures can be varied in order to provide a broad range of performance benefits in many types of formulations and chemistries. An attempt is made to clarify the general structure-property relationships that drive the performance attributes of siloxane additives and detail the continuum that exists between wetting, leveling, defoaming and slip within this chemistry class.

Principles of substrate wetting in Inkjet

Why certain wetting agents spread over certain substrates, and fail at wetting out other? What are the specifics of packaging substrates, and how do these differ from those made of natural polymers used to make porous materials such as paper, corrugated board and textiles? How are surfaces functionalized to improve their wettability? How important is the process dynamics for the selection of wetting agent? Answers to these and many more questions are provided as the topic of substrate wetting gets revisited from the ‘inkjet’ perspective.

Outperformulate your waterborne inks - Part I

Recorded Webinar: Inks are often produced from semi-finished to address the application complexity and reduce the final production step to a blending operation. Semi-finished must not only be intermixable and compatible but also stable over the time. In this mini webinar series, challenges and solutions are presented. The first part presented solutions for pigment preparations and particle stabilization, so how to control the color and appearance of an ink. Part 2, will be related to foam, slip, release and substrate wetting - so control of the physical parameters of an ink.

Star products – substrate wetting agents for Inkjet

Substrate wetting agents modify the static surface tension profile of fluids, thus impacting the rate of coverage and the final coverage ratio of the fluid. Process dynamics and the character of the surface being printed on call for quite a specific set of surface active wetting agents. To prevent the formulators from going through a pitfall of testing numerous substrate wetters, the selection had been narrowed down to a handful of additives to address the needs of all ink technologies met in the inkjet space, selected according to the most important criteria in the industry: functionality, health and safety, and compliance to relevant regulatory regulations.
