Where is the difference between water-based paint with solvent paint

First of all, from the composition and environmental protection: 'emulsioni paint is the main type of waterborne architectural coatings. Emulsioni paint is mainly composed of water, emulsion, fillers and various additives. Solvent-based coating by resin, pigments and fillers, solvents and various additives. You can see that the water-based coating dispersion medium is water. After coating and coating, water and a small amount of additive to evaporate from the coating, with environmental protection, safety performance. Solvent-based coating dispersion medium is organic solvents. Coating in the most volatile organic solvents are toxic and harmful substances, is not only harmful to human body and natural environment. In terms of the chemical and physical properties of coating: coating than some of the physical and chemical properties of solvent coating, such as chemical resistance, weather resistance, contamination resistance, etc. As a result, the service life of coating long as solvent coatings. However, water-based coatings are also some high-grade products: such as silicon a crylic-acid coating, fluorocarbon coating, etc. Service life can reach 10 - 15 years or so. From the perspective of construction environment: in the construction environment, construction of water-based coating general requirements above 5 ℃, solvent coating can also be above 0 ℃ construction. Therefore, solvent coating can be used in winter near the north. In terms of basic requirements: water-based paint construction at the grass-roots level should be less than 10% moisture content, solvent coating construction at the grass-roots level should be less than 8% moisture content. Water-based coating has good air permeability, the water vapor in the grassroots can spread outward. However, solvent coating film density. If the base of high moisture content, water vapor not volatilize from the film, blister easily. Can be seen from the above, waterborne coatings in the field of environmental protection has more advantages than solvent-based coating, but water-based coatings in the field of physical properties and construction environment as solvent coatings. According to the current domestic market development trend of the coatings, water-based paint has the advantages of long-term development, more in line with sustainable development.
