Basic information:
Butyl, or sec-butyl acetate, also known as butyl acetate. It can dissolve a variety of resin and organics.The properties of Sec-butyl acetate and other isomers are similar in most cases, the biggest differences are that its boiling point is lower than n-butyl and isobutyl, and its evaporation is faster.
