Problem with thinner formulation

Dear sir,

I am a chemical engineer. I have formulated a NC thinner which is very much suitable for wood finishing. but the problem is that it is not stable. After few days I am receiving complaints that it is sticks in the spray gun, initially it is not having problem. The following: acetone, toluene, IPA, methanol [affil links].

Awaiting your response as early as possible.

I'd suspect the methanol as the culprit to your sticky problems. Are the spray guns cleaned before everybody goes home at the end of the night? I would think flushing the guns with a cleaning thinner, or acetone ⇦ this on eBay or Amazon [affil links] Warning! highly Flammable! for that matter, would solve your problem.

Actually the NC thinner has add of normal butanol(NB). less methanol or acetone.

Q. Hello sir,
I have a question about nc thinner that some whitish thing is formed in the thinner. Can you please suggest some measures to remove this thing? I think this has happened because of the moisture, but I am not sure.
Would appreciate the answers.
