Abstract

A system and method for coating a substrate (102), the system including integrated powder coating material preparation (130, 140) and deposition (122) of powder coating material onto the substrate (102). The system includes a feed input (130) that processes the powder coating materials for use in a filament extension atomizer (140). The filament extension atomizer (140) stretches fluid filaments of the powder coating material to form droplets (144) of powder coating material. The droplets (144) of powder coating material are partially cooled to prevent agglomeration and to form a powder coating material suitable for electrostatic deposition. The cooled powder coating material is electrostatically charged and directed onto the substrate surface, where it is deposited due to the electrostatic potential between the substrate and cooled droplets. The deposited powder coating material is then cured to the substrate to form a cohesive film of coating material across the substrate.
