Electrostatic Powder coating on glass

Electrostatic Powder coating on glass

Electrostatic Powder coating on glass

(OP)

I was wondering if it is possible to use electrostatic
powder coating on glass. IF yes, what is the manufacturing
process for it ? Any pre-treatment required ?
What are the equipment necessary for this process ?

Glad to have your advice,

Salsa

RE: Electrostatic Powder coating on glass

Electrostatic (powder) coating on glass is going to be tricky at best.  First of all, you need the part to be coated to be able to carry a negative charge.  Glass, being the non-conductor that it is will have adverse effects.  There are other ways to "simulate" a charge on a non-conductive part.  You may want to try using a conductive blank behind the part such as a piece of sheet metal.  The coating will be attracted to the blank but will apply to the surface of the glass just in front of it.  Different types of powder coating need to be investigated as well.  A ultra-violet curable coating probably won't help you much unless you apply some sort of primer to the glass first so it will stick.  A heat sensitive powder might be the better solution.  You could heat the part to the appropriate temp and that should "liquify" so to speak the powder being applied.  You might want to consult with people from applications specialists like Nordson, or ITW Ransburg to further help you in this matter.

We may be able to help you.  Our company recently designed a fluidized bed system for the application of a powder coating to irregular shaped parts.  The same technology would work in your application.  Contact Russell Husfeld or Alan Nix at 1-800-228-3217

What add advantages are you looking to gain by powder coating glass? PPG Industrial Coatings may be able to help; they are the leader in equipment. You may have one problem though, there is a high cure temperature and it may break the glass.

We have powdercoated a great deal of glass.  No problem!  Simply preheat the glass to 300F for about 7 minutes, powder coat and cure.  

We have coated: christmas tree ornaments, clay pots, bottles and more.  

There is a great site with free powder coating info at: TechnicalHelp4U.com
