n-Propyl acetate vs. Isopropyl acetate

[Leonardo Teixeira]

Hello,

I've been reading that there is a trend of increased use of n-propyl acetate as replacement of, for example, ethyl acetate, MEK or toluene on both gravure and flexo inks. Yet, I could not find any mentions on isopropyl acetate following the same path. Is there a reason for that on the technical side? Isopropyl acetate has a evaporation rate smaller than n-propyl acetate and its higher rate is said to improve printing quality and reduce overall costs when compared to ethyl acetate. Is it sufficient to justify such trend?

Thank you!
