Читать книгу Additives for Water-borne Coatings - Wernfried Heilen - Страница 13

The complex demands made on wetting and dispersing additives in water-borne coatings make it necessary to combine electrostatic repulsion and steric hindrance. This is called electrosteric stabilisation and modern wetting and dispersing additives for water-borne systems work on this principle. Only such additives can fulfil the high demands made on pigment stabilisation and long-term storage stability (Figure 2.2c).
