Diethylene Glycol (DEG)

Diethylene Glycol (DEG) is a colorless, odorless, and hygroscopic organic compound with the chemical formula C4H10O3. It belongs to the family of glycols, which are diols (compounds with two hydroxyl groups). DEG is a versatile chemical used in various industrial applications, but it is essential to handle it with care due to its potential toxicity.

Resins: Diethylene Glycol (DEG) is used as synthesizing agent for alkyd resins as well as saturated and unsaturated polyester. Diethylene Glycol (DEG) is used in the synthesis of polyurethane resins, as a coalescence agent, anti-freezing agent in polymer and/or acrylic homopolymer emulsions, chain extender and agent in the dispersion and wetting of unsaturated polyester resins.
Synthesizing agents: Diethylene Glycol (DEG) can be used as synthesis intermediate. Diethylene Glycol (DEG) esters are used as emulsifiers. Diethylene Glycol (DEG) esters with fatty acids (oleic, stearic, lauric, etc.) are used as emulsifiers and plasticizers of polymers.
Wetting and plasticizing agents: Diethylene Glycol (DEG) can be used as wetting and plasticizing agent In the production of cellophane, glues and adhesives, textiles, printing ink, leather, cosmetics, paper and pharmaceutical products
Coolant additives: Diethylene Glycol (DEG) can be used in antifreeze formulations in proportions of up to 10% together with MONOETHYLENEGLYCOL. The various quantitative ratios between these components are suitable for specific applications in the field of industrial refrigeration.
Cement additive: Diethylene Glycol (DEG) can be used as an auxiliary additive in cement milling. It can be used in extremely small proportions to produce significant results, increasing the hourly production of cement without increasing the energetic demand on the system.
Brake fluids: Diethylene Glycol (DEG) can be used as secondary solvent in brake fluid formulations. This products is also used to avoid the excessive swelling of rubber in the hydraulic system.
Other uses: Ethylene glycols can also be used in the formulation of printing ink, in the treatment of gases, in the formulation of fire-resistant hydraulic fluids, in the formulation of cutting oils, in the formulation of surface polishers, in the formulations of agrochemicals, in the extraction of solvents, in the manufacture of pigmented pastes and putty for walls, and in the synthesis of explosives.
