From the composition and environmental protection, said:
The main varieties of water-based architectural coatings are latex paints. Latex paint is mainly composed of water, lotion, pigments and fillers and four kinds of additives; and solvent-based paint composition is resin, pigments and fillers, solvents and various additives composed of four parts. It can be seen: the dispersion of water-based paint medium is water, paint construction, from the coating of volatile water and a small amount of additives, with environmental protection, safety and other properties; and solvent-based paint dispersion medium is organic solvents (generally referred to VOC), from the coating of volatile organic solvents are toxic and hazardous substances, not only harm the human body, but also the natural environment pollution.
From the physical and chemical properties of the coating speaking:
Some of the physical and chemical properties of waterborne coatings are less than solvent-based coatings, such as chemical resistance, weatherability, stain resistance and the like. So the use of water-based paint without solvent-based paint long. But the water-based paint also has some high-grade products: such as water-based silicone C coatings, fluorocarbon coatings, the service life can reach l0 a l5 years.
From the construction environment point of view:
In the construction environment, the construction of water-based paint generally requires more than 5 ℃ construction, solvent-based paint can also be constructed in the O ℃, so the northern region, close to the winter can use solvent-based paint for construction.
From the requirements of the grass-roots level:
Water-based paint construction of the grass-roots moisture content should be less than l0%, solvent-based coating construction base water content should be less than 8%. Water-based paint permeability is better, the grass-roots water vapor can spread outside; and solvent-based coating film dense, if the grass-roots moisture content, water vapor can not be volatile from the film, easy to blister.
As can be seen from the above, water-based paint than the solvent-based coatings in environmental protection has more advantages, but the physical and construction environment, the water-based paint is less than solvent-based paint. On the current domestic paint market trends, water-based paint more long-term development advantages, more in line with sustainable development.
