Outperformulate your waterborne inks - Part I

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 are presented. The first part presented solutions for pigment preparations and particle stabilization, so how to control the color and appearance of an ink. Part 2, will be related to foam, slip, release and substrate wetting - so control of the physical parameters of an ink.

Unlock new possibilities by using engineered silica in printing inks

Recorded Webinar: As the printing industry advances towards higher printing speeds and a broader range of graphic effects, the utilization of both fumed and precipitated silica in printing inks has become prevalent. The choice of particle sizes and surface treatments plays a crucial role in influencing the ink formulation's matting effect and rheology behavior. This presentation aims to explore the benefits of using engineered silicas such as AEROSIL®, ACEMATT®, SIPERNAT®, and SPHERILEX® in printing inks applications. The discussion will focus on how these silicas can enhance key properties like Rheology Control, Matting, Anti-block, and scratch resistance in the ink formulations.
