Excellent compatibility with water-based systems including emulsions, coatings, and industrial cleaners.
Low dosage efficiency — effective at 0.05–0.3% w/w in most formulations.
Thermally stable up to 120°C, maintaining performance under elevated processing temperatures.
Non-yellowing and non-staining, suitable for clear and light-colored end products.
Architectural and industrial waterborne paints and coatings.
Textile printing pastes and dyeing auxiliaries.
Agrochemical formulations including suspension concentrates (SC) and emulsifiable concentrates (EC).
Industrial cleaning agents and metalworking fluids.
Adhesives, sealants, and construction mortars.
