How to Select a Carbon Black Dispersant? Key Points for Dispersing Carbon Black and Conductive Paste
Carbon black, with its fine particle size, high specific surface area, and strong electrostatic agglomeration, is one of the most challenging pigments to disperse in waterborne pigment concentrates and conductive pastes. This article analyzes the difficulties of carbon black dispersion,…
Differences Between Dispersants and Wetting Agents and Their Combined Use
Wetting agents address powder wetting and substrate spreading, while dispersants ensure long-term particle dispersion stability. This article compares their mechanisms and selection criteria, and presents a recommended combination path using Toynol® FS-204 acetylenic diol, Superwet series, and DS/ADS dispersants, along…
How to Choose Wetting Agents for Waterborne Coatings? Dynamic Surface Tension is Key
The key indicator for selecting wetting agents in waterborne coatings is dynamic surface tension: it directly affects powder wetting, grinding efficiency, and dispersion stability. This article explains the mechanism of wetting agents, compares three types of surfactants (acetylenic diols, polyethers,…
