Powder coating is a dry finishing process using finely ground particles of pigment and resin. The particles are electrostatically charged and sprayed onto electrically grounded metal parts. The charged powder particles adhere to the parts and are held there until melted and fused into a smooth surface coating in a curing oven.
Before coating, the parts are cleaned and pretreated through a 8 Stage Pretreatment Process in-line with the coating and curing operations. The powder may be a thermoplastic or thermoset polymer that creates a hard finish paint, which is tougher than conventional paint.
