Definition - What does Water-Thinned Coating mean?
A water-thinned coating is a coating where the binder is dissolved or dispersed in water. Since water is the main vehicle, these coatings can also be thinned (i.e., their viscosity reduced) by adding water to help dispense the coating onto the substrate. One of the most common examples of a water-thinned coating is latex paint.
Corrosionpedia explains Water-Thinned Coating
Water-thinned coatings have many desirable properties, such as fast drying speed, and the ability to completely cover one color with another.
However, perhaps the greatest advantage of water-thinned coatings is their ability to be cleaned easily using water, which eliminates the need for hazardous solvent-based thinners. Also, these coatings do not possess flammable contents, significantly reducing the probability of fires and explosions in hazardous environments.
Water-thinned coatings also possess excellent resistance to alkalinity, allowing them to be used on unaged concrete and masonry.
