AndTech to Hold Zoom Seminar on June 24: "Slurry Dispersion/Aggregation Mechanisms, Zeta Potential Evaluation, and Stabilization Design via Powder Surface Modification"

AndTech Co., Ltd. (Headquarters: Kawasaki City, Kanagawa Prefecture; Representative Director and President: Masao Toyama, hereinafter AndTech), as part of its R&D development support, will explain "stabilization design" related to "slurry dispersion/aggregation mechanisms."

The stability of slurries is crucial, with control over the powder-liquid interface being paramount.

This course will first organize the basics of dispersion/aggregation mechanisms and zeta potential, and then explain dispersion stabilization techniques through powder surface modification, such as surfactant adsorption, polymer adsorption, and coupling treatment.

Participants can learn design guidelines applicable to a wide range of fields, including battery materials, electronic materials, and ceramics.
