Powder coating is a type of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a "skin". The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint.
Powder coating is applied as a free-flowing powder in a completely dry form. Think of it as paint with the solvent part removed. The coating is applied electrostatically and then cured under heat which causes it to form a kind of “skin.” Usually powder is used to coat metals, but there are a number of potential applications.
Powder coating is becoming one of the most wanted surface finishing techniques now a days. The definition of powder coating is the process of applying dry paint to a part. In comparison to normal wet painting such as house paints, the solids are in suspension in a liquid carrier, which must evaporate before the solid paint coating is produced.
Powder coating is a term used to describe a particular finish or base. It starts out as a fine powder. This powder consists of finely ground particles of pigment and polymer resin. After application to a surface, the powder is chemically altered with heat to create a finishing film.
