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.
Appearance: colorless, flammable, with fruit flavor liquid
Application:
1.used as solvent in coating industry.
2.used as solvent in printing ink,adhesive agent.
3.used as the reaction intermediate in the production of resin.
4.used as a cleaning agent.
5.used as a component in diluents.
