For example, powder coating commonly used for painting the appliance, automotive parts, metal doors, building structures. The popularity of the method is easily explained by the set of virtues which he possesses. First, the powder coating significantly reduces the cost of processing the metal. Paint consumption is less than traditional staining is approximately 2 times.
At the same time, the special design of the working chamber can reduce the percentage mass loss of 1%. Such a result is achieved due to the fact that the paint particles are not settled on the surface workpiece, do not remain in the chamber, and again collected by means of special devices and re-used in powder coating. Finally, to achieve the desired effect is sufficient to cover the metal thin coat of paint, rather than apply it in several stages, as is often the case with traditional staining. Secondly, the powder coating creates a durable and reliable coverage, which does not cleave and not erased from the surface, and also resistant to weather conditions. In addition, powder coating protects against rust. The effect is achieved through special techniques consolidate the coating.
After the painting is heated to temperature 150-220 C (average) deposited material melts and forms a solid layer. Some paints are called thermoset, upon heating start chemical reactions. The coating has can not be re melt or dissolve. Learn more on the subject from msd drug. Third, paint, powder coating varied. They produced a wide color gamut, and can have different textures and effects: gloss or matt surface, covering metallic or imitation marble – all this can be created with a powder paint. And one more important factor – the powder coating does not use solvents and paint myself all the time in inside a closed working chamber. Therefore, evaporation, which can harm health, here are minimal.
