Powder coating is a kind of coating which is in the form of fine powder. It has two different forms with general coatings. It does not use any solvent, so it is called powder coating. Powder coating has many advantages, high efficiency, effective saving resources, no harm to the environment, mainly divided into two kinds of thermosetting powder coating and thermoplastic powder coating. Thermosetting powder coatings are composed of low polymerization degree resin, with very low molecular weight, very good leveling, good decoration, anticorrosion and good mechanical properties, so thermosetting powder coatings develop faster than thermal plasticity.
At the same time, we need to pay attention to the problem of powder coating curing. When the powder coating is cured, it must be baked in accordance with the standard temperature and time. If the temperature is too low or the time is too short, the powder will not form the pattern, and the mechanical properties will be affected by the bad. Therefore, we must pay attention to the temperature and time when curing.
