Powder coating is a revolutionary way of applying veneer on surfaces. The dry powder is coated on a surface then heated in an oven till it reaches its melting point. The powder covers the surface and gives an even layer of impressive coat that makes the surface more resistant to scratches, breakage, UV rays and corrosion compared to ordinary liquid painting.
The equipments used in this approach are categorized into two: the electrostatic coating wherein the powder is introduced to the target location employing tribo or corona charging guns and fluidized bed wherein a container with air cavity at the bottom is filled with powder which is utilised for sticking pre-heated coating to the surface of the object to be applied with powder coating.
Substrate or layer preparation
This is the main step towards achieving a profitable powder coating. Free of charge the area from oil traces, lubricants, oxide remnants and other blemishes on the target substrate.
If there are any stains on the surface, you can apply various forms of cleaning tactics depending on the substrate, the kind of blemish and the size of surface to be cleaned. In addition to that, check the components to make confident it is not dangerous to your health.
For wooden, plastic and glass surfaces, you can apply sandblasting even though silicon carbide grit is utilized on non metal components. For steel surfaces like beams, a cast steel shot is used to prepare the surface from powder coating.
The powder utilised for coating is made of grounded colour particles. The particles are charged and squirted to the surface electrostatically. The particles are grounded electrically in order for them to stick strongly to the surface area till the procedure is accomplished.
This is an critical approach wherein soon after the powder is applied on the topic, it is placed in an infrared cure or convection cure oven and is subjected to around 200 degree Celsius for ten minutes. In this approach the powder coating is melted and allowed to react chemically for it to stick to the substrate permanently.
By utilizing the correct equipment, you can obtain a difficult finish that sticks to the paint tougher than standard painting method. Its reputation is due to the fact that it resists to chemical compounds, does not call for any solvent and is environment-friendly.
