In which industrial applications is nonionic bitumen emulsion preferred over cationic or anionic types?
Nonionic emulsions are chosen in specialty cases where charged systems become unstable due to additives, fillers, or highly variable water chemistry. They can be useful in certain coating and primer formulations, some waterproofing systems, or blends where ionic interactions cause unpredictable breaking. Nonionic systems may provide more tolerance to specific contaminants but can have different adhesion behavior on aggregates compared to cationic systems. Because road applications generally rely on controlled charge interaction, nonionic grades are less common there and should be selected only with strong stability data and substrate trials.
