Product Detail Page — High-Purity Solvent, CAS 111-55-7
1. Product Overview
Ethylene glycol diacetate (EGDA; also written ethylene diacetate, glycol diacetate or 1,2-diacetoxyethane) is the diester of ethylene glycol and acetic acid, supplied as a clear, colorless liquid with a mild, pleasant ester odor. With two acetate groups on a compact C2 backbone (CH₃COOCH₂CH₂OOCCH₃), it combines strong solvency with a high boiling point and slow, even evaporation.
This balanced profile makes EGDA a workhorse high-boiling solvent in coatings, printing inks, adhesives and cleaners — and a widely adopted “green” replacement for cyclohexanone, isophorone and DBE (dibasic esters) in solvent systems that demand better leveling, lower VOC load and more consistent film formation.
A single raw material, four core value propositions:
● Coatings & Paints — active and coalescing solvent for nitrocellulose, alkyd, acrylic and epoxy systems; improves leveling, gloss and dry-film quality;
● Printing Inks — slow-evaporating solvent for gravure, flexographic, screen and electronic/PCB inks;
● Adhesives & Cleaners — solvent and coalescing aid in adhesives, industrial cleaners, degreasers, paint strippers and polish formulations;
● Chemical Intermediates — raw material for plasticizers, foundry resin hardeners and tobacco humectant systems.

3. Key Features & Benefits
● High-boiling active solvent: boiling point 186–190 °C and slow, even evaporation improve leveling, flow and gloss while reducing pinholes, brush marks and solvent pop in coatings and inks.
● Strong solvency across resin families: readily dissolves nitrocellulose, alkyd, acrylic and epoxy resins — a practical drop-in alternative to cyclohexanone, isophorone and DBE in many formulations.
● Low-volatility, low-odor profile: keeps VOC contribution low and working environments more acceptable than with lighter, more aggressive solvents.
● Easy to formulate: fully miscible with common organic solvents and compatible with standard resin systems, simplifying solvent blends and clean-up.
● Stable and consistent: chemically stable under normal storage; ≥99% assay with controlled acidity and water content gives batch-to-batch reproducibility.
● Flexible supply: custom assay, color and packaging options from drum to IBC to ISO tank, with COA for every shipment.
4. Main Applications
4.1 Coatings & Paints (Core Application)
EGDA is a classic high-boiling ester solvent for solvent-borne coating systems:
● Nitrocellulose lacquers — active solvent that replaces lower-performance diluents and improves flow and gloss;
● Alkyd, acrylic and epoxy industrial coatings — coalescing/leveling solvent for wood, metal and plastic substrates;
● Automotive refinish and coil coatings — controlled evaporation for uniform film build;
● Paint strippers and coating removers — high-boiling component that keeps the active layer wet and effective longer.
4.2 Printing Inks
● Gravure and flexographic inks — slow-evaporating solvent for gloss, adhesion and printability;
● PCB solder-resist and electronic inks — controlled drying with low residue for circuit-board processing;
● Screen-printing and stamping inks — stable viscosity and clean release.
4.3 Adhesives, Cleaners & Auxiliaries
● Adhesive formulations — solvent and plasticizing coalescer, including PVA (white glue) systems;
● Industrial cleaners, degreasers and paint thinners — high-boiling solvent component with good solvency and slower evaporation;
● Floor polish, leather polish and leather brightener formulations;
● Tobacco industry — practical substitute for triacetin (glycerol triacetate) as a humectant/casing solvent in filter and casing systems.
4.4 Chemical Synthesis & Other Uses
● Organic synthesis intermediate — acylation and ester-exchange feedstock;
● Plasticizer intermediate and internal plasticizer in polymer systems;
● Foundry industry — organic ester hardener component in acid-cured no-bake resin systems;
● Fragrance and flavor compounding — carrier/masking solvent where high-purity ester grades are required.

● Fast response: quotations and technical support within 24 hours; small trial orders accepted.
It is mainly used as a high-boiling solvent in coatings and paints, printing inks, adhesives, cleaners and degreasers; as a coalescing aid in polish and leather formulations; and as a raw material/intermediate for plasticisers, foundry resin hardeners, tobacco humectant systems and organic synthesis in general.
They are different chemicals. Ethylene glycol diacetate (CAS 111-55-7) is the diester of ethylene glycol with acetic acid — a high-boiling, slow-evaporating solvent. Ethylene glycol (CAS 107-21-1) is a diol used mainly as an antifreeze base and polyester monomer. They are not interchangeable in any formulation.
No. Diethylene glycol diacetate has an additional ethylene oxide unit in the chain (molecular formula C₈H₁₄O₅ vs C₆H₁₀O₄) and different physical properties. Always confirm the exact CAS number before substitution.
As an industrial raw material it can irritate eyes and skin, and it is a combustible liquid. Handle with gloves and safety goggles, keep the area ventilated, avoid inhaling vapors, and keep away from open flames and ignition sources. It is not intended for food use. Refer to the MSDS supplied with each shipment for full handling and first-aid guidance.
