Methyl glycol ( ethylene glycol monomethyl ether ( EGMM ), 2- methoxyethanol ) is a colorless, sweet-smelling liquid from the group of glycol ethers, which was used as a solvent for paints, coatings and resins.
Properties
Ethylene glycol monomethyl ether is a flammable, air-sensitive colorless liquid with a pleasant odor, which is miscible with water. It decomposes when heated, with irritating vapors and gases, and has at 20 ° C, a conductivity of 1.09 · 10-4 S / m.
Use
Ethylene glycol monomethyl ether is used as a solvent for coatings, for the production of very highly concentrated coating solutions as a solvent in the production of circuit boards and for the dyeing of leather. It is found in industrial paint cleaners and cleaners for surfaces and also serves for the production of oven-drying industrial coatings and methylglycol.
Safety
The vapors of ethylene glycol monomethyl ether may form (39 ° C, ignition temperature 285 ° C flash point) with air to form an explosive mixture.
Methylglycol has mainly a toxic effect on the germinal epithelium of the testes and the embryonic and fetal tissue in the uterus. Thus, methyl glycol has a teratogenic effect.
After the discovery of the teratogenic action of this substance a substitution process has taken place, which has meant that this solvent is no longer used for coating materials and in consumer products in industrial coatings only in small amounts.
