The difference between electrophoresis coating and powder coating surface treatment
Dec 09, 2016


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 mainly used for coating of metals.



Electrophoresis is the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field.The technique applies a negative charge so proteins move towards a positive charge.It is ultimately caused by the presence of a charged interface between the particle surface and the surrounding fluid.
