Ethylene glycol diacetate (EGDA) is an important organic chemical raw material, which is widely used in coatings, inks, adhesives, plastics, fibers and other fields. This article will detail the properties and uses of ethylene glycol diacetate.

1. the properties of ethylene glycol diacetate

ethylene glycol diacetate is a colorless transparent liquid with a pleasant aroma. It is soluble in ethanol, ether, acetone and other organic solvents, slightly soluble in water. The chemical properties of ethylene glycol diacetate are relatively stable, and it is not easy to undergo oxidation, reduction and other reactions, but it is easy to hydrolyze under acidic conditions.

In addition, ethylene glycol diacetate also has the following properties:

1. Low toxicity: ethylene glycol diacetate has low toxicity and belongs to low toxicity chemicals.

2. High boiling point: Ethylene glycol diacetate has a high boiling point and is not volatile, so it has good storage stability.

3. good film-forming: ethylene glycol diacetate has good film-forming, can be used as coatings, inks and other film-forming substances.

2. the use of ethylene glycol diacetate

ethylene glycol diacetate as an important organic chemical raw material, in the field of chemical production raw materials has a wide range of uses, mainly used in the following aspects:

1. Coating industry

ethylene glycol diacetate can be used as a coating film-forming material, with pigments, fillers, etc., can be made into a variety of properties of coatings, such as alkyd resin coatings, acrylic coatings. These coatings have good weather resistance, water resistance, chemical resistance and other properties, can be used in construction, automobile, furniture and other fields.

2. Ink industry

ethylene glycol diacetate can be used as ink connection material, with pigments, fillers, etc., can be made into a variety of printing inks, such as letterpress ink, lithographic ink. These inks have good printability, drying, abrasion resistance and other properties, and can be used in various printing processes.

3. Adhesive industry

ethylene glycol diacetate can be used as one of the main components of the adhesive, and can be used in conjunction with polymers, tackifiers, etc., can be made into various adhesives, such as hot melt adhesives, pressure sensitive adhesives Wait. These adhesives have good bonding strength, water resistance, heat resistance and other properties, can be used in wood processing, packaging, construction and other fields.

4. plastic industry

ethylene glycol diacetate can be used as a plastic modifier, with the use of polymers, fillers, etc., can improve the performance of plastics, improve its processing performance and use performance. For example, the toughness, strength, heat resistance, and the like of the plastic can be improved.

In conclusion, as an important organic chemical raw material, ethylene glycol diacetate has a wide range of uses in the field of chemical production raw materials.
