Black and White Silicone-Modified Polyester Powders for Cold-Rolled Steel Appliance Trial Panels
Both powders have a median particle size (D50) of 32–40 µm. The supplier lists density at 1.42–1.50 g/cm³ for white and 1.45–1.52 g/cm³ for black. For 0.8 mm cold-rolled steel trial panels, the sheets specify phosphating/passivation, 50–60 kV corona spraying, a 50–60 µm dry film and a 15-minute hold once the part metal reaches 200 °C. Validate the actual assembly and separately confirm suitability for its intended contact conditions.
