Paper: The best for red and yellow – a new additive technology for waterborne iron oxide concentrates

In decorative coatings the use of pigment concentrates is a modern and flexible way to produce colored paints. Especially in waterborne applications these concentrates have to be compatible with a broad range of different binder technologies. Because of that the concentrate formulations are usually free of binder and highly compatible. Furthermore the demands in terms of storage stability, color strength and cost efficiency are very high. These demands are directly conferrable to the used additive technology. The additive has to give outstanding viscosity reduction to achieve highest pigment loads and most economic grinding, it has to stabilize the pigments over a long period of time without any change in rheology and it has to develop the color to the maximum to avoid any waste of expensive pigments. The most important pigment class in decorative coatings are the iron oxides. Iron oxides are not difficult to wet but because of the shape iron oxide yellow tends to give dilatant rheology which can be a disaster when it comes to automatically dosing in a dispensing machine. Iron oxide red tends on the other hand to change the color shade over time. This article introduces new findings concerning iron oxide pigments and their use in binder-free pigment concentrates. It discusses advantages and disadvantages of using classical additive technologies for iron oxide pigments. It introduces a technology that combines a polymeric structure with phosphate groups to achieve the outstanding viscosity reduction of polyacrylate salts and the long term stability of high polymeric additives. In the end advice and guidelines for formulating iron oxide pigment concentrates is given.

Recording: Dispersion Week 2: Optimization of wet dispersing and comminution processes for pigmented systems

Recorded Webinar: We were delighted to offer a joint webinar with NETZSCH-Feinmahltechnik GmbH, the world's leading company in the field of wet grinding, dispersion and homogenization as well as mixing and kneading. For the production of paints, coatings and inks, a wide variety of raw materials must be processed into complex formulations. This requires various process steps in which the different components must be mixed, homogenized and ground to a defined particle size distribution. In the lecture, various processing options, advantages and disadvantages as well as optimization potentialshad been discussed and complete solutions had been presented. This webinar was part of the Dispersion Weeks.

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.
