Paint knowledge | difference between water-based paint and solvent paint

Core tip: the main type of water-based building coating is latex paint Latex paint is mainly composed of water, emulsion, pigments and fillers and various auxiliaries four parts The solvent coating is composed of resin, pigment and filler, solvent and various additives It can be seen that the dispersing medium of water-based coating is water After coating construction, water and a small amount of additives are volatilized from the coating film, which has environmental protection and safety properties The dispersing medium of solvent based coating is organic solvent (generally referred to as VOC) Most of the organic solvents volatilized from the coating film are toxic and harmful substances, which will not only harm the human body, but also cause pollution to the natural environment From the Physicalization of film Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Home of coatings: the main type of waterborne building coatings is latex paint Latex paint is mainly composed of water, emulsion, pigments and fillers and various auxiliaries four parts The solvent coating is composed of resin, pigment and filler, solvent and various additives It can be seen that the dispersing medium of water-based coating is water After coating construction, water and a small amount of additives are volatilized from the coating film, which has environmental protection and safety properties The dispersing medium of solvent based coating is organic solvent (generally referred to as VOC) Most of the organic solvents volatilized from the coating film are toxic and harmful substances, which will not only harm the human body, but also cause pollution to the natural environment In terms of the physical and chemical properties of the coating, some physical and chemical properties of the water-based coating are inferior to those of the solvent based coating, such as chemical resistance, weather resistance, stain resistance, etc Therefore, the service life of waterborne coatings is not as long as that of solvent based coatings But there are also some high-grade products of water-based coatings, such as water-based silicon acrylic coating, fluorocarbon coating, etc., with a service life of about 10-15 years In the construction environment, the construction of water-based coating is generally required to be more than 5 ℃, and solvent based coating can also be constructed at O ℃ Therefore, in the northern region, solvent based coating can be used for construction near winter For the requirements of the base course, the moisture content of the base course for water-based coating construction shall be less than 10%, and that for solvent based coating construction shall be less than 8% The air permeability of water-based coating is better, and the water vapor inside the base can diffuse outwards; while the film-forming of solvent based coating is dense, if the moisture content of the base is high, the water vapor can not be volatilized from the film, and it is easy to bubble Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
