N-Butyl acetate

Description

1. Product Overview

N-Butyl Acetate is a high-purity, fast-evaporating oxygenated solvent widely utilized in coatings, adhesives, printing inks, and industrial cleaning formulations. Its primary industrial function is to dissolve resins, nitrocellulose, and acrylics while enabling precise viscosity control and uniform film formation. The key value proposition lies in its optimal evaporation rate and solvency power, which deliver superior flow, leveling, and gloss in finished products. Strategically, N-Butyl Acetate is indispensable for manufacturers transitioning to high-solids, low-VOC compliant systems, making it a critical raw material for regulatory-driven markets globally.

2. Key Specifications & Technical Characteristics

• Chemical composition: N-Butyl Acetate (CH₃COO(CH₂)₃CH₃), CAS 123-86-4

• Purity grade: ≥99.5% (min) – Industrial Grade / High-Purity Solvent Grade

• Physical form: Transparent, colorless liquid

• Odor: Characteristic fruity (pear-like), low residual odor

• Density (at 20°C): 0.876 – 0.882 g/cm³

• Boiling point range: 124 – 127°C

• Evaporation rate (n-BuAc = 1.0): 1.0 (relative to butyl acetate standard)

• Water content: ≤0.05% (max)

• Acidity (as acetic acid): ≤0.01% (max)

• Packaging options:

  • 180 kg net new steel drum

  • 850 kg IBC (intermediate bulk container)

  • Bulk ISO tank (20,000 – 24,000 kg)

• Shelf life: 24 months in original unopened container, stored away from moisture and extreme heat

3. Core Industrial Applications

• Automotive & industrial coatings: Used as the primary active solvent in 2K polyurethane and acrylic lacquers – delivers faster flash-off times than PMA or xylene without compromising film hardness.

• Flexographic & gravure printing inks: Enables low-tack, high-transfer formulations; superior solvency for nitrocellulose and polyamide resins reduces print defects like pinholes and orange peel.

• Adhesives (packaging & footwear): Dissolves chlorinated rubber and cyanoacrylates quickly; provides open-time control critical for high-speed lamination lines.

• Pharmaceutical & agrochemical extraction: Serves as a low-toxicity process solvent in crystallization and purification steps – preferred over toluene or MEK for residue-limited applications.

• Industrial degreasers & electronics cleaning: Removes rosin fluxes and silicone oils without attacking polycarbonate or ABS substrates, unlike chlorinated solvents.

Why it outperforms alternatives: Faster evaporation than propylene glycol monomethyl ether acetate (PMA) for shorter drying cycles; higher flash point than acetone for safer handling; non-HAP status in most formulations reduces compliance burden.
