Diethylene Glycol Diethyl Ether

Diethylene Glycol Diethyl Ether is a clear, colorless liquid that is water soluble and has low odor. Diethylene Glycol Diethyl Ether is a suitable solvent for emissive applications such as coatings, inks, adhesives and in cleaning formulations. It is used in place of butyl ether acetates where odor is a concern, and in place of more volatile cleaning solvents.

Chemical Name: Diethylene Glycol Diethyl Ether

Applications:


Graphics arts – ink solvents:
Diethylene Glycol Diethyl Ether is useful in a variety of ink formulations, including inkjet inks that are stable and do not clog tiny orifices, high-end writing inks with low viscosity and good stability, conductive inks and pastes, as well as magnetic inks.

Diethylene Glycol Diethyl Ether is used in ink formulations to:
• Maximize color print quality and durability
• Increase cartridge reliability and endcap/idle times
• Eliminate odor and toxic solvents
• Minimize dispersant and pigment cost
• Choose boiling points to control droplet size and to concentrate dyes on the surface

Key Properties:
• High solvency provides stability and maximum color density
• Strongly complexes with pigments
• Low odor
• Prevents inkjet clogging
• Acts as an emulsifier and humectant

Aqueous coating compositions useful in coating substrates immediately after printing with oil-based inks contain Diethylene Glycol Diethyl Ether. These coatings accelerate bonding and drying of the ink, which permits faster printing.

Diethylene Glycol Diethyl Ether is also used in formulations of deletion fluids for positive printing plates, as retouching agents for lithographic printing, waterless lithographic plates, and in cleaning agents for removing inks from printing machines.Diethylene Glycol Diethyl Ether is useful as well in correction fluids and re-touching liquids for toner images, in photosensitive coating solutions in diazo processes, in alkaline processing solutions in diffusion transfer photography. For desensitizing compositions for pressure-sensitive copying paper. Additionally, they are used as low-odor white-board cleaners.


For Bright and durable Inks: Ink formulators use solvents as key ingredients to improve image appearance and durability. The ability of Diethylene Glycol Diethyl Ether to disperse pigments in aqueous and solvent-based systems enables formulators to reduce cost and increase ink stability. The choice of mix of medium boiling point controls evaporation rate, to keep the pigment or dye concentrated on the paper suface, for maximum color density.


Humectants as strong emulsifiers: The use of Diethylene Glycol Diethyl Ether improves cartridge life and idle (also known as decap) times. Being a strong emulsifier Diethylene Glycol Diethyl Ether is used to stabilize ink and function as humectant to keep orifices clear.

UV, wide-format, eco-ink and low-odor ink: Diethylene Glycol Diethyl Ether will increase solvency, decrease ink viscosity and allow printing on an extended range of materials such as polymer films. They also enhance the solvency of soy-based and ecosolv inks and allow ink formulators to improve performance to adapt to increasing demands for color fastness, optical density and sharpness.


Other Applications: Diethylene Glycol Diethyl Ether is also used as grease solvent for nitric acid fiber and woolen printing and dyeing as well as extraction agent for uranic product and solvent for organic complex.
