Been spraying the epoxy for several weeks, and I'm trying to figure out why when air is reintroduced into fresh epoxy within about a minute or less after laying it down it separates? I've sprayed several parts, test panels, masking paper and on every test panel when air is reintroduced to the fresh epoxy by blowing on it or using compressed air it seems to separate
Example I can spay a coke can with multiple passes NOT letting the paint stop flowing, let it set for a few minutes and the epoxy is fine.
I can perform the same test and the remove my mask and lighty blow on it and BOOM it separates. And no I'm not spitting on. I tried that too. Didn't separate.
I have attached a picture of three trigger pulls
From left to right.
1st blew on it within 2 seconds
2nd blew on it about 30 seconds
3rd didn't blow on it at all. NO separation. WHY??
