Abstract:

Various components, such as pigments, fillers, chemical additives, crosslinkers and rheology modifiers go into coating and paint formulations. To achieve especial decorative and functional properties of paints and coatings, the use of nanomaterials is essential. But only with even dispersed and deagglomerated nanoparticles, an improvement of the coating formulation can be realized. Ultrasound is an effective means for the dispersion and emulsifying, deagglomeration and milling of such components in coatings.
