Topic: Powder removal from masking

We currently use compressed air to blow the powder paint off of our masking pieces. Some are metal & others plastic/rubber.

My question is, what other methods are available (and affordable) that would do a better more consistent job. Right now we tend to get cross color contamination from several different styles of masking. They can be very difficult to remove all the powder from the crevices.

Any ideas??


Re: Powder removal from masking

Just so I'm clear, please tell us your process, step by step. From your description, I am assuming it looks like this:

mask part

spray part

remove mask

bake part

In my process, we leave the masks in/on the part all the way through the baking process. Once the powder has cured, we remove the mask and can reuse it with a minimum of cross-color-contamination. The cured powder flakes right off of the silicone masks, and the metal masks we can process through our strip line.

Re: Powder removal from masking

Cleaning metal powder coating masks and certain types of plastics such as polypropylene Teflon and nylon masks can be cleaned with our Eco-friendly MILES #8612 stripping solution/cleaner. After each powder color batch has run through the coating process, remove the mask from the production line and immerse it in room temperature MILES #8612 for a few minutes, then rinse with warm water and then use your filtered compressed air to dry and return to the powder coating line.
