Glycol Ethers Have Excellent Solvent Properties And They Are Used As Coalescing Aid And Coupling Agent In Paint Formulations

Glycol Ethers

Glycol Ethers are widely used as solvents in a wide range of applications, especially as coalescing aids and coupling solvents. They are highly soluble in water and organic liquids. They are also effective as solvents for paints, lacquers, dyes, resins and inks. They are also a major component of household and industrial cleaners, grease and paint removers, metal and hard surface cleaners and hydraulic fluids.

E-series ethylene Glycol Ethers are commonly used as solvents for lacquers, dyes, paints and enamels. They are also valuable as coating and cleaning agents in the semiconductor industry.

P-series propylene Glycol Ethers are also widely used as solvents for lacquers, paints and varnishes. They are also highly soluble in water and used as coating and cleaning agents in the semiconductor industry.

They are also used as a coalescing aid and coupling agent in paint formulations, particularly for water-based and solvent-based coatings. They are a good coalescent and effective in lowering the minimum film formation temperature (MFFT).

These substances are also used in hydraulic brake fluids as a solvent, a coalescing aid and an acidity regulator. They have a high boiling point and are a versatile industrial solvent.

The toxicity of the monomethyl ethers of ethylene glycol is moderate, similar to that of the alkyl ethers. Short-term exposure to low concentrations can cause dizziness, headache, confusion, fatigue, drowsiness and slurred speech. Long-term exposure can result in skin irritation, anemia and bone marrow suppression, encephalopathy and reproductive toxicity.

The monomethyl ethers of ethylene glycol are known to affect the male reproductive system, with testicular damage and reduced sperm count at higher levels. Inhalation and oral exposure to higher concentrations, particularly during pregnancy in animals, can produce a variety of birth defects, including resorption of fetuses, decreased fetal weight, and cardiovascular and skeletal abnormalities.

Inhalation of vapors from these compounds can result in coughing, breathing difficulties, dizziness, drowsiness, weakness, loss of coordination, a headache, and eye and nasal irritation. Exposure can also cause nausea and vomiting.

The acute toxicity of the monomethyl ethers is relatively low, whereas repeated contact or inhalation of vapors can lead to skin irritation and hemorrhage. Inhalation of very high concentrations can also cause a severe headache and slurred speech.

Huntsman Corporation and a leading polyols producer for polyurethanes from Korea, KPX Chemical entered in a joint venture in September 2021, for producing and delivering novel polyurethane system solutions for Korean automakers.
