Diacetone alcohol

Description

1. Product Overview

Diacetone Alcohol (DAA) is a high-purity, slow-evaporating ketone alcohol recognized globally as a superior solvent and coupling agent for high-performance coatings, resins, and industrial cleaners. Its primary industrial use lies in formulating nitrocellulose, epoxy, and polyurethane systems where controlled volatility and excellent blush resistance are critical. The key value proposition is its unique balance of hydrophilic and hydrophobic properties, enabling stable formulations in water-sensitive applications while reducing surface defects. Strategically, DAA is indispensable for manufacturers seeking to meet tightening VOC regulations without compromising on finish quality or application window stability.

2. Key Specifications & Technical Characteristics

• Physical characteristics:

  • Molecular weight: 116.16 g/mol

  • Density (20°C): 0.936 – 0.940 g/cm³

  • Boiling point: 164 – 168°C

  • Flash point: 58°C (closed cup)

  • Evaporation rate (n-butyl acetate = 1): ~0.15

• Shelf life: 24 months from production date when stored in original sealed containers at 5–40°C, away from strong oxidizers and direct sunlight

3. Core Industrial Applications

• Primary industries: Automotive coatings, industrial wood lacquers, printing inks, electronics cleaning, agrochemical intermediates

• Specific use cases:

  • High-solids coatings: Reduces viscosity in epoxy and polyurethane systems without raising VOC load

  • Nitrocellulose lacquers: Prevents “blushing” (moisture-induced haze) in humid spray environments

  • Lithographic and screen inks: Improves flow and leveling on non-porous substrates

  • Electronic component degreasing: Dissolves flux residues and rosin-based pastes without corroding sensitive metals

• Why it performs better than alternatives:

  • Compared to MIBK (methyl isobutyl ketone): Higher blush resistance and slower evaporation allow longer wet-edge time

  • Compared to glycol ethers: Lower toxicity profile and better resin compatibility in nitrocellulose systems

  • Cost advantage: Up to 12% lower cost per liter of active solvent versus specialty oxygenated solvents

4. Competitive Advantages
