The difference between water-based latex paint and solvent-based paint

Waterborne latex paint and solvent-based paint are commonly used coatings, which occupy a large share in the market, but it is often difficult to distinguish them when buying. So how different are these two coatings? The following briefly introduces some differences between water-based latex paint and solvent-based paint.

Different dispersion media

The dispersion medium of waterborne latex paint is water, while the dispersion medium of solvent-based paint is organic solvent (VOC).

Different environmental performance

After the construction of waterborne latex paint, water and a small amount of additives volatilize from the coating film, which has the performance of environmental protection and safety. The volatiles of solvent-based coatings are mostly toxic and harmful substances, which not only do harm to human body, but also pollute the natural environment.

Different physical and chemical properties

From the physical and chemical properties of the film, some physical and chemical properties of water-based latex paint are not as good as those of solvent-based paint, such as chemical resistance, weather resistance and stain resistance. Therefore, the service life of water-based coatings is not as long as that of solvent-based coatings.

Different requirements for the construction environment

Water-based latex paint coating construction generally requires construction above 5℃, and solvent-based coating can also be constructed at O℃, so solvent-based coating can be constructed in northern areas near winter.

Different grass-roots requirements

The moisture content of the base course of water-based coating construction should be less than l0%, and the moisture content of the base course of solvent-based coating construction should be less than 8%. Waterborne latex paint has good air permeability, and the water vapor inside the base can diffuse outward; However, solvent-based coatings are dense, and if the water content of the base material is high, water vapor cannot be volatilized from the coatings, and it is easy to bubble.
