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.

Recording: Outperformulate your waterborne inks - Part II

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 were presented. In the first part we have presented solutions for pigment preparations and particle stabilization, so how to control the color and appearance of an ink. Part 2, have been related to foam, slip, release and substrate wetting - so control of the physical parameters of an ink.
