Propylene glycol methyl ether ester (Propylene Glycol Methyl Ether Acetate, referred to as PGMEA) is a colorless transparent liquid with a light and elegant odor. It is an important solvent in the field of chemical production raw materials, widely used in coatings, inks, adhesives, cleaning agents and other industries. This article will detail the properties and uses of propylene glycol methyl ether esters.
1. properties of propylene glycol methyl ether ester
1. physical properties of
propylene glycol methyl ether ester is a colorless transparent liquid, elegant smell. It has a relative density of about 0.97, a boiling point of 143 ℃, a flash point of 43 ℃, a viscosity of 2.4mPa · s, a surface tension of 24.6mN/m, a refractive index of 1.4007, and flammability.
2. Chemical properties
propylene glycol methyl ether ester has good chemical stability, is not easy to hydrolyze, and is not easy to react with acid and alkali. It is non-corrosive to metal, but has a dissolving effect on some rubber and plastics. In addition, propylene glycol methyl ether ester also has a lower toxicity, belonging to the low toxic chemicals.
2. the use of propylene glycol methyl ether ester
1.
of the coating industry propylene glycol methyl ether ester is used as a solvent in the coating industry, which can improve the leveling, gloss and drying speed of the coating. It has good compatibility with resins, pigments, etc., and helps to improve the storage stability of the coating.
2. Ink industry
In the ink industry, propylene glycol methyl ether ester as a solvent can improve the fluidity of ink and improve printing performance. At the same time, it can also reduce the viscosity of the ink and increase the printing speed.
3.
of the adhesive industry Propylene glycol methyl ether ester is used as a solvent in the adhesive, which can improve the wettability and fluidity of the adhesive and improve the bonding performance. At the same time, it also helps to increase the drying speed of the adhesive.
4. cleaning agent industry
in the cleaning agent, propylene glycol methyl ether ester can be used as a solvent and cleaning agent, with good decontamination ability and cleaning effect. It can remove grease, stains, etc., and is suitable for cleaning metal, plastic and other materials.
In short, as an important chemical raw material, propylene glycol methyl ether ester is widely used in coatings, inks, adhesives, cleaning agents and other industries. Understanding its nature and use is of great significance to the rational use of resources, improve product quality and reduce costs. During use, it is necessary to pay attention to the safety and environmental protection of propylene glycol methyl ether ester, comply with relevant laws, regulations and standard requirements, and ensure the safety and reliability of the production and use process.
