Coating additives is a kind of important component material of coating products, it can improve the production process, improve product performance, improve the performance of coating construction, improve and improve the performance of coatings and films can play a very critical role, with the increasing attention to environmental protection, water-based coatings began to develop rapidly, water-based coating additives are more and more important by the people in the industry. So what do you need to pay attention to when choosing additives for waterborne coatings?
Wetting and dispersing agent
Solid and liquid contact, the original solid gas interface disappears, the formation of new solid-liquid interface, this phenomenon is called wetting. When wetting pigment filler with liquid, and making it penetrate into the pigment filler's appendage and aggregation, if a small amount of surfactant is added into the liquid, it is easier to wet and penetrate, and this is the wetting effect. The surfactant that makes the pigment filler wet or accelerates the wetting is called wetting agent. This kind of liquid in water-based paint is water.
The surface properties of pigment and filler, the type and dosage of wetting and dispersing agent as well as the efficiency of dispersing equipment are the main factors affecting the dispersion.
The stabilization or aggregation of pigment and filler suspension and dispersion system depends on the force between particles, repulsion and attraction. The repulsive force is the main factor for stabilization and the attractive force is the main factor for aggregation.
