Achieving stain-resistant properties for paints requires a combination of tailored polymer dispersions, balanced paint formulation ingredients and efficient use of rheology modifiers. To design such coatings a deep understanding of the involved mechanisms is important. In her paper “New Techniques to Understand Stain Resistance Properties of Waterbased Architectural Paints” Zeena Cherian describes a number of techniques with individual strengths and weaknesses and how to combine them for a better understanding of stain resistance.
Among the techniques she describes how to use molecular modelling simulations and Atomic Force Microscopy to study stain interaction and coating surface chemistry. Additionally, a technique based on Quartz Crystal Microbalance was used to study adsorption and de-sorption of stains.
