Paint knowledge | what is the difference between water-based emulsion paint and solvent based paint

Core tip: water based emulsion paint and solvent based paint are commonly used coatings, occupying a large share in the market, but it is often difficult to distinguish them when purchasing, so how different are the two kinds of coatings? Here is a brief introduction of some differences between water-based emulsion paint and solvent based paint Waterborne latex paint is mainly composed of four parts, such as water, emulsion, pigments and fillers and various auxiliaries 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 emulsion paint is water After coating construction, water and a small amount of additives are volatilized from the coating, which has environmental protection, safety and other properties Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Home of coatings news: both water-based latex paint and solvent based paint are commonly used coatings, occupying a large share in the market, but it is often difficult to distinguish when buying, so how different are the two kinds of coatings? Here is a brief introduction of some differences between water-based latex paint and solvent based paint Waterborne latex paint is mainly composed of four parts, such as water, emulsion, pigments and fillers and various auxiliaries 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 emulsion paint is water After coating construction, water and a small amount of additives are volatilized from the coating, which has environmental protection, safety and other properties; The dispersing medium of solvent based coating is organic solvent (VOC) Most of the organic solvents volatilized from the coating are toxic and harmful substances, which not only harm the human body, but also pollute the natural environment In terms of the physical and chemical properties of the coating, some physical and chemical properties of the water-based emulsion paint are inferior to those of the solvent based paint, 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 However, there are also some high-grade products of water-based emulsion paint, such as water-based silicone acrylic paint, fluorocarbon paint, etc., with a service life of about 10-15 years In the construction environment, the construction of water-based latex paint is generally required to be above 5 ℃, and solvent based paint can also be constructed at O ℃ Therefore, solvent based paint can be used for construction near winter in northern areas 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 emulsion paint is better, and the water vapor inside the base can diffuse outwards; while the film-forming of solvent based paint 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 The above are some personal opinions on the two coatings, hoping to help the users who are not familiar with the coating industry 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,
