Product Introduction
Ethylene Glycol Diacetate (EGDA) CAS 111-55-7
– High-Boiling Slow Evaporation Solvent for Industrial Coatings, Inks & Resin Formulations from China.
1. Introduction
Ethylene Glycol Diacetate, widely abbreviated as EGDA, is a low-toxicity high-boiling ester solvent with CAS number 111-55-7. It appears as a colorless, mild-odor transparent liquid with excellent dissolving power for acrylic, epoxy, polyurethane, alkyd and nitrocellulose resins. Characterized by slow evaporation rate, wide solvency spectrum and low surface tension, EGDA has become a premium universal solvent for high-end industrial coatings, printing inks and resin compounding, replacing toxic high-boiling aromatic solvents to meet global low-VOC environmental standards.
We operate a professional ester solvent manufacturing factory covering a total land area of 100 mu, equipped with fully automated continuous esterification synthesis lines, multi-stage vacuum rectification purification workshops, independent central QC laboratory and standardized full-cycle wastewater & solid waste recycling treatment stations. Our team consists of 150 skilled frontline production workers and 30 full-time professional technical engineers, responsible for raw material feeding, catalytic esterification reaction, distillation refining, full-batch index testing and environmental waste harmless disposal separately. We maintain long-term joint research partnerships with multiple universities and chemical environmental research institutes, focusing on green process optimization for a full range of industrial solvents including Ethylene Glycol Diacetate (EGDA). Our joint R&D projects focus on three core directions: low-waste catalytic esterification technology to lift EGDA purity and reduce alcohol/acid residual impurities, energy-saving vacuum distillation upgrades to cut carbon emissions, and closed-loop resource recycling systems for production wastewater and solid waste catalyst residues. Every batch of our EGDA maintains stable boiling range, ultra-low water and free acid content, perfectly matching formulation demands of automotive paint factories, wood coating manufacturers, printing ink compound plants and resin synthesis enterprises. We provide complete English export compliance documents, stable mass spot inventory and free coating formulation technical support for global chemical distributors and paint processing manufacturers.

8. FAQ
Q1: What is Ethylene Glycol Diacetate (EGDA) mainly used for?
A: EGDA is a high-boiling slow-evaporating ester solvent primarily applied as core auxiliary raw material for all types of industrial coatings. It is widely used in automotive paint, furniture wood varnish, metal anti-corrosion coating, gravure printing ink and resin synthesis, improving coating leveling, gloss and eliminating common film defects like pinholes and orange peel.
Q2: What unique production advantages does your EGDA manufacturing factory own compared with other solvent suppliers?
A: Our factory covers a total area of 100 mu, with 150 skilled production workers and 30 full-time professional technical R&D engineers. We maintain long-term joint research cooperation with multiple universities and chemical environmental research institutes, dedicated to green esterification process optimization for EGDA and a full series of industrial coating solvents. Our R&D team continuously upgrades product purity indicators and develops closed-loop recycling treatment technology for production wastewater and solid waste catalyst residues, providing low-impurity, low-VOC compliant EGDA and free coating formulation technical support for global paint manufacturers.
Q3: Is your EGDA EU REACH registered for bulk export to European coating and ink factories?
A: Yes, our EGDA substance holds complete ECHA EU REACH registration dossier with authorized EU Only Representative (OR). We can provide full batch SVHC test reports, low-VOC environmental certification and official compliance declaration to support smooth customs inspection in all EU member countries without detention risks.
Q4: What negative impacts will excessive free acid and water impurities in EGDA bring to finished coatings?
A: Excess free acid will accelerate paint pigment flocculation, cause finished coating film yellowing and reduce long-term weather resistance; high water content will lead to paint system turbidity, storage viscosity rise and spraying surface whitening defects. Our EGDA strictly limits free acid ≤0.03% and water ≤0.08% to completely avoid such production problems.
Q5: Can I get free lab test samples of EGDA before bulk order? Do you offer volume wholesale discount?
A: We supply small lab trial samples of EGDA for coating and ink formula testing and solvency performance verification. Competitive preferential unit prices are provided for long-term cooperative large paint factories and global chemical distributors. Our 30-person professional technical team offers free customized solvent matching optimization guidance for automotive, wood, anti-corrosion and printing ink production lines.
Q6: What is the shelf life of sealed EGDA liquid? What storage risks should be noticed?
A: Under tightly sealed cool, dry and ventilated warehouse storage conditions, the shelf life of EGDA reaches 24 months. EGDA is a flammable liquid with medium flash point; it must be stored far away from fire sources and oxidants. Loose packaging will absorb moisture and increase water content, affecting coating film quality during construction.
