Water-based metallic paints are generally not particularly high in the construction environment. They are widely used. They can be directly applied in wet exterior and wet environments, and have good adaptability to materials and coatings. The contents can be washed with water, which greatly reduces the consumption of the cleaning solvent, does not contain harmful substances, and does not evaporate into the air, so there is no defect such as yellowing, and it is more durable.
Under normal circumstances, the choice of water-based metal paint with tap water can be used, but in the case of very low temperature, tap water can not be directly used as a thinner, which will directly affect the drying speed of the paint, so you can choose to use about 50 degrees. Warm water, which can improve the drying speed of the top coat during construction, and the adjusted paint is placed in the warm water basin, which is convenient for construction and can provide the surface film forming effect.
Or you can mix alcohol with warm water, usually a ratio of one to one. This method is very good for the construction of the primer, which can enhance the leveling of the paint and avoid the drawbacks of the paint film. A certain humidity is a necessary condition for the construction of water-based metallic paint. If the temperature is too low, the drying will be too fast, which will affect the leveling effect of the paint film. If the humidity is too high, the drying will be too slow, and the paint film will simply show cracking, whitishness or other Disadvantages, usually suitable for humidity of 40% -80%.
In addition, it also has certain requirements on the temperature. When the surface is sprayed, the temperature of the surface of the substrate should be greater than 5 °C. If it is lower than 5 °C, do not spray the topcoat, and the construction of the waterborne metallic paint can not be too thick. It is very simple to show the phenomenon of cracking or color distribution. Therefore, construction workers should pay attention to the selection of thinner and environment, and strictly follow the construction principles of coatings.
And it has the following special
The first is odorless, non-polluting, and does not pose any harm to human health, and truly achieves environmental protection.
Non-flammable, non-explosive, easy to transport.
Dilute with tap water, construction materials, equipment, and containers are also cleaned with tap water, greatly reducing the cost of painting.
The drying time is fast, the work efficiency is improved, and the labor cost is reduced.
Wide range of applications: automotive, shipbuilding, grid, machinery manufacturing, containers, railways, bridges, wind turbine blades, steel structures and other industries.
