Its chemical formula is C₆H₁₂O₂ (structural formula: CH₃COOCH(CH₃)CH₂CH₃) and CAS number is 105-46-4. As a medium-boiling ester solvent, SBAC features moderate evaporation rate, excellent solvency for resins and polymers, and low toxicity, making it a preferred environmentally friendly alternative to butyl acetate, toluene, and xylene in coatings, inks, and adhesives industries.

Key Applications

Coatings Industry (Core Use): SBAC is a versatile solvent for alkyd resins, acrylic resins, polyurethane coatings, and nitrocellulose lacquers. Its medium evaporation rate balances film formation speed and leveling performance, reducing surface defects such as pinholes, orange peel, and blushing. It is widely used in automotive refinishing, architectural coatings, and industrial anticorrosive coatings, replacing high-VOC solvents like toluene and xylene.

Printing Inks: Used as a solvent for gravure inks, flexographic inks, and screen printing inks. It improves pigment dispersion and ink adhesion to substrates (paper, plastic, metal), and its low odor makes it suitable for food packaging ink formulations.

Adhesives & Sealants: Serves as a solvent for contact adhesives, pressure-sensitive adhesives, and structural sealants. It enhances the bonding strength of adhesives to wood, plastic, and metal surfaces, and complies with low-VOC regulations for construction and packaging adhesives.

Chemical Synthesis Intermediate: SBAC is a raw material for producing sec-butanol via hydrolysis, and is used as an extraction agent for natural products (e.g., essential oils, flavors) due to its good solubility and low residue. It also acts as a reactant in organic synthesis for producing pharmaceuticals and pesticides.

Cleaning Agents: Applied as a degreasing agent for metal surfaces, electronic components, and precision instruments, effectively dissolving grease, wax, and organic contaminants without causing corrosion.
