Badger Stynylrez Primer Clogged My Airbrush
Posted by mightypudge on Sunday, September 12, 2021 9:40 PM

Basically, like the subject says. 

Until today, I've been using mostly Mr. Surfacer 1500. However, after hearing much praise about Badger Stynylrez, I figured I'd pick some up from Amazon and give it a shot.

Before using, I shook the bottle well and then took the cap off to check the consistency. I noticed right away the viscosity was pretty high. Definitely not "skim milk" consistency. In fact, a bunch of the stuff was sort of congealed inside the cap. Okay. I followed the directions on the bottle: no thinning, 25-30 psi, 0.5 needle. 

I could barely get the stuff to shoot for a few seconds, when my airbrush clogged. I thought, "tip drying already?" Nope. The stuff seemed to turn the consistency of chewing gum inside my airbrush and paint cup. It took me nearly an hour to clean the AB. The paint cup was so caked in congealed primer, I thought I'd never get it clean.

I took a second stab, this time thinning it 50/50 with 91% IPA, but got the same results. Another hour cleaning the AB.

Is it possible I got a bad batch?

Yes, this is not normal behaviour for Stynylrez IMO.

What is ICA? If you cleaned or flushed with it and it isn't compatible with Stynylrez, maybe it caused or added to the trouble?

It seems like Stynylrez has a lot of "bad batches".  Even guys that have been succesful in the past run into the gummy mix with enough frequency that it leads me to believe Badger's quality control is more miss than hit.  I emailed them several months ago about a "bad batch" of 6 different color bottles.  No response beyond the automated one.

Sorry, that should be IPA. I updated my original post.

Ok, I'll do a quick test and get back with you. Thanks for the correction.

IPA will thin it or clean it. Not my first choice for thinning but it will do it. Without knowing more about the mixing of the bottle it sounds like bad paint.

Now that said, if that bottle sat for a long time in some odd possition the stuff does settle, so you could have glop at the top rather thanBut Stynylrez is thicker than your average milk consistancy, still sprays nice if it's good. I do it that pretty often but I also thin it with lacquer thinner, to which it dries egg shell smooth with a slight sheen.

So I just mixed a some Stynylrez with 70% IPA. It didn't gum up immediately but it does not mix, it separates.

I can't say anything for sure other than I've never heard of anyone using alcohol to thin or clean Stynylrez.

I guess if it were me I'd clean the a/b (full tear down) and flush with water, then try one more time with the Stynlyrez neat. Everything else you did is same as I do (pressure, nozzle, neat)

Good luck getting this sorted out.

I saw one video of someone using IPA to thin it and tried it. As I said, it sprays but not the results I like ( I didn't let it sit long enough to experience separation). As to cleaning I use soap and water or Fantastic. Then I follow up with water, then alcohol shot though as a final to get the water out basically. Also on a Q Tip 91% IPA will cut dried Stynylrez . The Paasche H sometimes will get some dried in the air cone out front and I'll use IPA for that. I mostly use the H for priming with it. I have used the Badger 200 as well though, even with the .25 tip. It did ok but liked it better thinned a bit.

For the record a Badger video I watched said not to thin but if you feel that need for your given condition to just use water. I find thinning with water looks good till you feel the surface and find you really should scuff the fuzzies off. Someone mentioned lacquer thinner, I thought no way lol. Then tried it, been doing that ever since if I want it thinned.

I use Stynylrez all the time and always thin it about 60/40 with ipa anywhere from 50%-90% and get great results and an easy cleanup. But, I have read reports of Stynylrez freezing in cold weather and it gets completely ruined, although I have not experienced this myself.

I use IPA as well, with a drop of flow improver. Mixing the paint thoroughly  is critical. As mentioned the paint settles, and from my experience, into a gloppy goop. I have been able to revive that stuff but I had to mix it extremely well. I am talking a powered mixer sort of mix.

Yes and this may be the issue depending how the bottle sat. My Stynylrez black needs mixing again right now actually. Last time was about a year ago, at which time I was using black a lot and shaking the bottle 1-3 times a week after that mix.But now it's sat for most of the summer. The stuff won't really mix back together with a stirrer, not fully anyway. I use a Badger power mixer on it. I think last time I used it ( the black) was back in July or so and it's fully separated now.

Badger have recently posted in a Facebook modelling group about the composition of the Stylnyrez and have said that recently they were using different "ingredient" due to not being able to source what they were using originally. They are saying that now they have managed to find a source of the original "ingredients" and have released some of the new batch for testing. Reputedly the new brew is performing as it originally did.

I had purchased Black, Grey, Glosss Black & White early 2020, and had no issues with any of them, sprayed at 20psi through an Iwata Eclipse-0.35mm needle.

Then i ran out of white in June this year bought some and the difference was staggering.

Tip dry, nozzle clog, gummed up brush. I even in desperation bought a 0.5mm nozzle & Needle. Still had major issues.

Hopefully they will rectify the situation as when it works i think it is a great product, especiaally as i am "restricted" to using acrylics
