Non-ionic emulsions are used when ionic interactions can cause instability or unpredictable breaking, such as with certain additives, specialty fillers, or sensitive substrates. They may be selected for niche coating systems, primers, or specialty “creams” where controlled film formation is more important than rapid aggregate bonding. In practice, non-ionic systems are less common in road works and more likely in industrial coatings or formulations that must remain stable across a wider range of chemistry conditions.
