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.
DAMEI’s two January 2025 technical sheets describe silicone-modified polyester trial powders for cold-rolled steel. Both specify a median particle size (D50) of 32–40 µm. The white powder has a listed density range of 1.42–1.50 g/cm³ and the black powder 1.45–1.52 g/cm³.
The listed setup uses 0.8 mm cold-rolled steel with phosphating/passivation pretreatment, 50–60 kV corona application and a 50–60 µm dry film. Hold for 15 minutes after the metal reaches 200 °C. Record actual metal temperature and measured thickness. Validate the assembled part and its intended contact conditions separately.
Use the related product and buyer guidance to compare chemistry, substrate, pretreatment, finish, cure and test scope. DAMEI can then confirm the current formulation and sample plan for your application.
