PFA Powder For Electrostatic Spraying

Electrostatic spraying is an advanced coating process where powder is atomized into a fine and uniform shape by compressed air, and then uniformly adsorbed onto the surface of a metal workpiece by a high-voltage electric field, and cured into a film at high temperature. 

Rely on outstanding characteristics, PFA powder is widely used in electrostatic spraying process, particularly suitable for applications requiring anti-sticking and chemical resistance under high-temperature conditions.
