2-Methoxyethanol

Description

1. Product Overview

2-Methoxyethanol is a high-performance glycol ether solvent characterized by its dual hydroxyl and ether functional groups, enabling exceptional solvency for both polar and nonpolar compounds. It is primarily used in industrial coatings, semiconductor photoresist stripping, and printed circuit board manufacturing, where controlled volatility and high dilution ratios are critical. The key value proposition lies in its ability to improve production throughput by reducing drying defects and residue formation. Strategically, it remains essential in specialty chemical supply chains despite regulatory oversight, due to limited cost-effective alternatives for specific high-precision applications.

2. Key Specifications & Technical Characteristics

• Chemical composition: Ethylene glycol monomethyl ether (C₃H₈O₂), CAS 109-86-4

• Purity grade: Industrial grade ≥99.5% / High-purity electronic grade ≥99.9%

• Physical characteristics: Clear, colorless liquid; mild ethereal odor; density 0.965 g/cm³ (20°C); boiling point 124–125°C; flash point 39°C (closed cup)

• Packaging options: 200 L steel drums (net 190 kg), 1000 L IBC totes, and ISO tank containers (20 MT)

• Shelf life: 24 months from date of manufacture when stored in sealed, original containers away from moisture and ignition sources

3. Core Industrial Applications

• Coatings & printing inks (primary industry): Used as a retarder solvent in nitrocellulose and epoxy coatings to prevent blushing and improve leveling. Provides faster release than propylene glycol ethers, reducing oven dwell time by 12–18%.

• Electronics manufacturing: Essential in positive photoresist strippers and edge-bead removers for semiconductor wafers. Outperforms ketone-based solvents by leaving lower trace metal residues (≤5 ppb).

• Chemical intermediates: Precursor in the synthesis of 2-methoxyethyl acetate and specialty acrylates. Higher reaction yield (≥94%) compared to ethanol-based routes due to better nucleophilic stability.

• Industrial cleaning: Effective flux removal in PCB assembly. Lower surface tension (28.5 dyn/cm) than isopropanol, enabling under-chip cleaning without high cavitation energy.

4. Competitive Advantages

• Quality consistency: Batch-to-batch purity controlled within ±0.1% via gas chromatography; each shipment includes Certificates of Analysis conforming to ASTM D-3644.

• Supply reliability: Multi-plant production (Asia, Middle East) with 99.3% on-time-in-full delivery rate over 24 months; buffer stock held in Rotterdam, Houston, and Singapore.

• Logistics capability: Compatible with hazardous-class UN 1188; specialized temperature-controlled shipping for electronic-grade material.

• Commercial positioning: Priced 6–8% below European and US incumbents for equal or higher purity, with volume-tiered rebates for annual contracts above 500 MT.

• Technical support: Full material compatibility guides, VOC compliance data (EU Directive 2010/75/EU), and safety data sheets in 12 languages.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 MT (bulk / ISO tank) or 4 x 200 L drums for spot buys (760 kg)

• Bulk loading capacity: 20 MT per 20-ft ISO tank container (utilizing 100% of payload without requiring flexibags)

• Note: Drum and IBC orders require a minimum of 1 full pallet (4 drums / 1 IBC). Electronic-grade pricing available on request with lead time 14–21 days.
