“We produce coating powders such as LDPE, HDPE, PP, NYLON. One of my customers is asking whether Nylon 6 or 66 can be electrostatically coated on metals used for automotive parts. If possible, what size particle is best suited for an electrostatic spray-coating system? “


“Electrostatic spray grade Nylon is normally ground to a particle size distribution of 20 to 40 microns. Larger particles are OK, but smaller particles are more difficult to pump and charge. Your customer may have to use a positive polarity corona charging powder gun. This is important since 99% of all powder coating guns are negative polarity. Past experience has proven that Nylon accepts a positive charge more readily. “
