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.
