Define Powder Coating Powder Coating is the type of coating which does not require solvent as a liquid carrier like conventional liquid paint coating. It emits very minimal Volatile Organic Compounds (VOC) as compared to liquid form paint coating process. It is considered as an environmental friendly Green coating technology. There are some critical de-greasing, cleaning, rinsing and pre-treatment process of the substrates prior to applying powder coating. The best with high quality assurance of powder coating is the entire coating process with automated computer aid control system from cleaning, pre-treatment with non-toxic chemicals to coating. It will minimize possible human errors compared to manual or semi-manual powder coating process.
