The characteristics of the water-based coating compared with solvent paint
Source: China coating network
With the rapid development of the Chinese paint market, water-based paint also gradually occupies a certain position in the coating market. But according to the China coating procurement network small make up to know, now many consumers do not have a correct understanding of waterborne coatings on choosing water-based paint and solvent coating is in doubt. Compared with solvent paint water-based coatings has the following features:
1、Water-based paint electrophoresis coating evenly, level off. Good flattening; Lumen, weld, edges and corners, edge parts can be coated with a certain thickness of the film, have very good protection; Electrophoretic coating has the best corrosion resistance, salt fog resistance of thick film cathodic electrophoretic coating of up to 1200 h.
2、Water-based paint with water as solvent, save a lot of resources; In construction of water-based coating to eliminate fire hazard; Reduced to atmospheric pollution; Waterborne coatings using only a small amount of low toxicity of ethanol and organic solvents, improves the operation environment conditions. General coating of ability in organic solvents (coating) between 10% ~ 15%, and now the cathodic electrophoretic coating has fallen below 1.2%, save resources to reduce pollution.
3、Water-based paint coating tools available water cleaning, greatly reduce the cleaning solvent consumption.
4、Coating on the surface wet and humid environment can be coated directly construction; Good adaptability to water-based coating on the surface of a material, coating adhesion.
The water-based coating has a lot of advantages, but it also has a fatal weakness, such as the construction process and material surface cleanliness requirement is high, because the water's surface tension, dirt make the coating produces shrinkage, relatively paint film is not as beautiful, oil paint and expensive price, is not so good water-based paint, oil paint environmental protection the drawbacks and water-based paint, oil paint is, therefore, the author suggest that consumers in the process of selection, can according to their own requirements, rational choice.
