The official definition of painting is that it is a liquid, liquefiable composition of the mastic (adhesive) solutions, after being applied in a thin layer on a 'substrate', a film becomes opaque and solid. It may be obvious if it is to say that painting is more commonly used for color, texture protect or to surfaces or objects, however, whether to think of the many items that the paint is applied to, that ranging from walls, cars and canvas, it is logical that there are many variations and types of paint used for his purposes. For example, the paintings are sold in hardware stores to be applied to the walls of the home will naturally have a different chemical composition to the face painting for children, since the former would require a higher degree of water resistance in order to be fit for purpose.
One such difference between the types of paint is the means by which it applies. In the case of industrial paints, for example, paint is applied as a solid and more in the form of a fine powder before being cooked at too high a temperature. The intense heat melts the powder and causes it to adhere (stick) to the surface to which it is applied. The reasons for the application of paint in this manner (commonly known as "Powder Coating") deal with the chemistry of paint, the same surface and possibly even the chemistry of objects in general is being painted (the substrate) yes!
The application of industrial coatings in this way has several advantages over the traditional approach to painting and conventional fluids. For example, powder emit little or no volatile organic compounds (also known as volatile organic compounds), which are chemical compounds that have significant vapor pressures can be harmful to the environment, as well as having adverse health effects human. Other advantages of powder coating as a means of painting include the fact that this method can result in a thicker layer of paint that is achieved without running or sagging, as would occur with the use of liquid paint. Moreover, the fact that coating overspray can be recycled means that the coating powder can lead to almost 100% of the layer being effectively used, an advantage for any industrial company in these times of austerity measures are required.
