  • Powder Coating and Particle Size Measurement

    The ProcessThe ProblemThe SolutionCapabilitiesThe powder coating process starts with application of a charge to an object's surface, usually by an electrical ground. At first, the powder coating is given a charge that is opposite to the charge applied to the object, and then the powder is directed toward the object in an air stream under pressure. When the powder particle comes closer to the charged object, electrostatic attraction controls and attaches the powder to the item. Initial handling, recovery, and recycling of the powder can increase fines, which ca
  • Particle Size and Shape Analysis of Powder Coatings
