Features Of BASF Dehydran 1293 Defoamer

Highly effective silicone-based defoamer for rapid foam knock-down in demanding aqueous systems.
Excellent long-term foam suppression performance, even under elevated temperature and shear conditions.
Good compatibility with anionic, nonionic, and amphoteric surfactants commonly used in industrial formulations.
Low dosage efficiency—effective at concentrations as low as 0.01–0.1 wt% depending on system severity.
Stable dispersion without phase separation during storage or in-process use.
