Posted by: FEIHONG Powders |on May 30, 2012

Critical Variables	Corona	Tribo
Faraday Cage	More difficult to coat recesses	Easier to apply to recesses
Back Ionization	Easier to coat thinner films	Easier to produce thicker films
Products configuration	Not good for complex shapes	Very good for complex shapes
Production requirements	Wide range of line speeds	Good for lower line speeds
Powder Chemistry	Less dependent on chemistry	More dependent on chemistry
