Do powder coated parts drip, run, or sag?
As the powder passes through the spray gun, the powder is given a negative electrical charge. The part to be powder coated is grounded or positive. Powder exits the spray gun in a fog like fashion and is attracted to the positive (grounded) part. This is one of the major differences between wet and dry paint. Wet paint is blown onto a part with a lot of pressure; powder is sprayed with low pressure causing the fog (Cloud) to be gently pulled to the part. The advantage is the fog reaches all recessed areas (like between the fins of a head, providing a more complete and uniform layer), which results in a smooth finish typically without the runs, sags, light spots, etc., that can occur with wet paint.
