Pre-Treatment? 

+

I am looking to start up a small powder coating job shop. My question pertains to systems I have had quoted. Which pre-treatment system has the broadest appeal and why? One system has a media blast system and the other has a chemical pre-treatment system.

The answer to your question depends on a number of factors. However the main thing you will have to take into consideration is what kind of substrate you will be coating. If you are starting up a job shop and do not know this I would recommend the chemical pre-treatment. A media blast system may be too aggressive for certain substrates and some systems can ingrain foreign objects (grease, oil) into the substrate rather than clean it. However there are a number of chemical pre-treatments and you will have to look into the type of chemical treatment more carefully.

I'm sorry I could not give you a definite answer but I would require more information on your circumstances.

I feel the pre-treatment chemical wash is the best way to go. If you will be doing a lot of different parts the media blast could hurt certain surfaces.

Good Luck!!! Sincerely,
