Solvent-Based Paint Handling?

[G D Beck]

Hi folks,

I just bought some SB-3000 paint from Lureworks.  They have great support, as some of you know, can't say enough good things about their service and knowledge.  The purpose of the SB-3000 is to lock in some color shifts without the thickness of clear dipping and with more flexibility on where the coverage is applied.  So, here is the surprise (to me anyway) and the reason for this post.  The SB paints are made of some pretty harsh chemicals (THF, MEK, CHx, and Phthalate).  Now that's a potent brew!  So, it turns out that chemical compatibility is limited, and there not many materials that work with this stuff.  Meaning, you shouldn't mix in most plastics (PEEK may be exception).  You can mix in glass, but now there are additional cleaning steps.  I'd prefer a disposable option for mixing.

So, has anyone developed a simple airbrush system for handling these solvent-based paints?  I'm kind of thinking about just mixing directly in the airbrush reservoir using glass eye droppers to measure ratios.  I also bought some 3-layer chemically resistant gloves for better protection (nitrile & latex are not recommended).  The SDS is attached here, as is a glove compatibility chart.  But bottom line, these are some strong paints that need to be used with care & caution, respirator and ventilation.  Any advice would be appreciated.

Yes all the sb coat stuff is potent. I don’t handle it any different than mek or acetone. Nitrile gloves and ventilation that doesn’t spark.‘I mix in my airbrush cup.‘I use clear and plastisol colorant to make custom colors. Just mix it in the cup and shoot. I use an iwata eclipse.
