Sec-butyl acetate is one of the 4 isomers of butyl acetate, which is an achromatic, inflammable and fruit-tasting liquid, and soluble to a variety of resins and organic matters. Its properties resemble other isomers under most circumstances. The biggest difference when it is used as solvent lies in its lower boiling point than common n-butyl acetate and isobutyl acetate, featuring fast evaporation.

Application scope
(1) Used as paint solvent. In terms of the properties, *-butyl acetate is similar to n-butanol acetate and isobutyl acetate. It is well soluble to many matters, and can be used to
substitute butanol acetate and isobutyl acetate to make solvents such as nitrocellulose lacquer,
acrylic paint, and polyurethane paint. It can also be used as quick dry agent for
photosensitive material. In metallic finishes, butanol acetate can be used to dissolve cellulose
acetate butyrate.
(2) Used as a solvent during the course to make synthetic resin.
(3) Used as a solvent during the course to make paint solidifiers.
(4) Used as a thinner, which is an ideal component to lower costs, and toxicity during the course
to make thinners such as Tiana, banana oil, etc.
(5) Used in ink. It can be used as a volatile solvent when making printing ink, replacing n-butanol acetate.
(6) Used as a solvent replacing n-butanol acetate when making cohesive.
