what is the difference between powder coating and liquid paint coating

Source: hongda Browse:255 The release date:2022.08.12 [ Large medium small ]

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.”

Liquid coating advantages

·         Low VOC products are available, allowing you to bring some liquid coatings products into regulated areas.

·         Liquid coatings can be applied at lower film builds, which means less coating is required, which can be an economic advantage.


Types of Paint


Paint is a mechanical dispersion mixture of one or more pigments, a liquid that contains non-volatile film-forming materials, oil drying and a dilute highly volatile solvent.

And An electrostatic paint is a type of spray coating that is used to efficiently coat a metal substrate by inducing an electrical charge to the paint particles that make up the spray, causing the paint to adhere to the metal's oppositely charged surface.

Electrostatic painting allows for reduced loss of paint due to overspray. There is up to a 98% transfer rate when using electrostatic painting compared to the 40% efficiency then it more save cost and VOC reduction.
