Sec-Butyl Acetate, often referred to in the industry as 2-Butyl acetate, is a colorless, flammable liquid ester utilized primarily as a versatile organic solvent in coating formulations. Verified under CAS 105-46-4, this solvent features a fruity odor and is chemically derived from secondary butyl alcohol. It is extensively applied in the manufacture of nitrocellulose lacquers, acrylic enamels, and polyurethane coatings, serving as a cost-effective alternative to n-Butyl Acetate and Methyl Isobutyl Ketone (MIBK) due to its specific evaporation rate and strong solvency power. We offer this 99% industrial-grade solvent in drum packaging with competitive factory pricing to support the paint, coating, and printing ink industries. Our supply chain ensures reliable bulk supply availability and customized specifications, fully accompanied by MSDS, TDS, COA documentation for strict safety handling and compliance.

FAQ - Technical & Supply Chain
-
Q:
Does Sec-Butyl Acetate correspond to the standard n-Butyl Acetate or the branched Isobutyl isomer?
A: Sec-Butyl Acetate is verified under CAS 105-46-4 as the ester of secondary butyl alcohol (2-butanol), distinguishing it from the linear n-Butyl Acetate or Isobutyl Acetate to ensure the faster evaporation rate and specific solubility parameters required for quick-drying lacquers. -
Q:
Why is Sec-Butyl Acetate frequently used as a replacement for MIBK or n-Butyl Acetate in solvent blends?
A: Sec-Butyl Acetate is typically applied as a cost-effective active solvent because it offers similar solvency for resins like nitrocellulose and acrylics but often falls outside of HAP (Hazardous Air Pollutants) restrictions, making it an environmentally favorable choice for compliance-driven formulations.
