Sec-butyl Acetate (butyl ester, butyl acetate, acetic ester ...)\Sec-butyl acetate (SBAC) is one of the four butyl acetate isomers. It is a colorless, flammable liquid with odor and it can dissolve many sorts of resin and organic matter.Normally, the property of sec-butyl acetate is similar with other butyl acetate isomers.1. To help grow business with this new products. 2. To help maximize strengths to stay ahead in paints. 3.

Used as solvent in coating industry. As one of the new environmental solvent, Sec-butyl Acetate is added into the old solvent mixtures to reduce the dosages of those more expensive solvents (especially the NBAC).Till now, Sec-butyl Acetate is most used in the nitrocellulose lacquer, acrylic acid lacquer, polyurethane lacquer, polyester lacquer, amine and epoxy paint, ect. 2. Used as solvent in printing ink. 3. Used as solvent in adhesive agent. 4. Used as the reaction intermediate in the production of resin. 5. Used as a cleaning agent. 6. Used as component in diluents.
