Not really. After 40 years of using solvents of a longer list than I take here to list, I'm pretty sure I might actually know about their uses.
BTW, Dupont 3919S is
Hydrotreated heavy naphtha (petroleum) 48 - 59%
1,2,4-trimethyl benzene 1% boiling point over 300F
Cumene (isopropylbenzene) 0.2% boiling point over 300F
Ethylbenzene 0.2% boiling point over 276F
Any concentration shown as a range is to protect confidentiality or is due to batch variation.
Non-regulated ingredients 40 - 50%
OSHA Hazardous: Yes
and those high boiling small percentage benzene derivatives are going to leave a film.
You want to use something that's going to go away......within your lifetime.
