Main Application Fields
Coatings and Ink Industry:
Solvent and Cosolvent:
As a "coupling solvent," it dissolves resins (e.g., acrylic resins, epoxy resins) and improves coating wettability on substrates (metal, plastic), widely used in automotive paints, wood coatings, and industrial anti-corrosion coatings.
Regulates ink drying speed to prevent defects like "orange peel" or "crater," especially in printing inks and UV-curing systems.
Typical Formula: Adding 5%-15% 2-isopropoxyethanol to acrylic coatings reduces system viscosity and enhances film uniformity.
Electronics and Semiconductor Industry:
Cleaning Agent: High-purity products (electronic grade, ≥99.5%) clean precision electronic components and PCB surfaces from grease, solder residues, and flux, leaving no residue after evaporation.
Photoresist Solvent: Dissolves photoresist polymers (e.g., PMMA) to ensure coating leveling and resolution during photolithography.
Metal Processing and Cleaning:
Additive for Water-based Cutting Fluids: Acts as a cosolvent to enhance compatibility between oil phase (mineral oil) and water, while providing anti-rust properties for cutting and grinding of aluminum alloys and steel parts.
Industrial Cleaner: Formulates water-based cleaners to remove lubricants, wax, and fingerprints from mechanical parts, especially for aerospace precision components.
Cosmetics and Personal Care:
Cosmetic Solvent: As a cosolvent in hair sprays and nail polishes, it dissolves polymer film-forming agents (e.g., PVP) and regulates product volatility to avoid uneven application from rapid drying.
Skin Penetration Enhancer: Low addition (<=5%) enhances the skin permeability of active ingredients (e.g., vitamins, drugs) for topical formulations or skin care serums.
Textile and Leather Industry:
Dyeing Assistant: Improves dye (e.g., disperse dyes) penetration into fibers, enhancing dyeing uniformity, especially for high-temperature and high-pressure dyeing of polyester fibers.
Leather Coating Agent: Dissolves polyurethane resins as a solvent for leather surface coatings, enhancing gloss and flexibility.
Safety and Toxicity
Acute Toxicity:
Oral (Rat): LD50 = 2000-3000 mg/kg (low toxicity, but immediate medical attention is required for ingestion).
Inhalation: High-concentration vapors (>1000 ppm) irritate the respiratory tract, causing headache, dizziness, and nausea; long-term exposure may damage liver and kidney function (OSHA PEL-TWA: 50 ppm, 8 hours).
Skin Contact: May cause mild irritation; prolonged contact can lead to skin dryness and defatting; wear protective gloves (recommended nitrile rubber gloves).
Environmental Hazards:
Biodegradable under aerobic conditions (decomposed by microorganisms into CO2 and water), but high concentrations are harmful to aquatic life (LC50 (fish): >100 mg/L); avoid direct discharge into water bodies.
Safety Operation Recommendations:
Store in a cool, ventilated place away from ignition sources (low flash point, anti-static measures required).
Operate in a fume hood or environment with local exhaust ventilation to prevent vapor accumulation.
Fire Extinguishing Media: Carbon dioxide, dry powder, foam; do not use water (may spread fire).
Summary
2-Isopropoxyethanol is a versatile glycol ether solvent valued for its excellent solvency, water compatibility, and moderate volatility, playing a critical role in coatings, electronics, and metal processing industries. Despite its toxicity and flammability, its high efficiency and mature environmental treatment technologies make it irreplaceable in industrial applications. In the future, low-toxic and biodegradable glycol ether derivatives may gradually emerge as green chemistry advances, but isopropoxyethanol will remain a key basic chemical raw material in the short to medium term.
