Water-based coatings, as the name implies, are coatings that use water as the main solvent or dispersion medium. For example, our common latex paints are water-based coatings. Solvent-based coatings are coatings obtained using organic solvents as a dispersion medium.
First, environmental protection
Compared with solvent-based coatings, water-based coatings have one solvent as water and one solvent as organic matter. It is conceivable that water-based coatings have better environmental protection performance and can achieve zero formaldehyde volatilization. Solvent-based coatings will cause organic volatilization during construction. Seriously endanger the environment and people's health. Therefore, the country vigorously promotes environmental protection, and water-based coatings have developed rapidly.
The construction of water-based coatings requires strict control of the temperature, humidity, and moisture content of the substrate. Under some harsh conditions, high-quality coatings cannot be obtained. The solvent-based paint can adjust the proportion of the solvent according to the construction environment of the construction site, so as to achieve an ideal coating film state. Because the objective needs and functions require the solvent-based paint to still occupy a part of the market, the solvent-based paint is still in terms of application. More dominant.
Water-based paint uses water as the solvent, which eliminates the fire danger during the construction of the production process, improves the working environment, and occupies an advantage in safety. However, solvent-based coatings can easily cause explosions and fires during production, storage, and transportation because they contain volatile substances in organic solvents. So in terms of safety, water-based coatings are stronger than solvent-based coatings.
