Surface Week 2: Improving Surface Appearance and Durability with SPHERILEX® Particles

This presentation describes how novel SPHERILEX® silica particles can be used to improve the surface appearance and wet scrub, burnish, stain, and metal marking resistance of architectural paints. It will also discuss how to boost the performance of traditional silica matting agents to achieve deep matte wood coatings that have significantly improved scratch, burnish and mar resistance.

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.
