Topic: Powder Coat Spitting

I am having a problem right now with a couple metallic colors spitting on finished parts.  The spitting is pretty excessive.  We have tried everything we can with our equipment, nozzles, etc.  We have been spraying these colors for quite some time and I'm not sure why all of sudden it is an issue.  I think it might be the extreme heat and humidity we are having right now.  Anyone know if this is possible.  Thanks!


Re: Powder Coat Spitting

Humidity is your culprit here.  Are you spraying in an air conditioned area?  Are you using a fluidized bed?  Is the hopper fed with moist, compressed air?  Is your air source dry?  Really, really dry?
