Dipropylene Glycol

Chemical Name: Dipropylene Glycol

General Applications:

The major end use for Dipropylene Glycol is as a raw material in the manufacturing of unsaturated polyester resins. Dipropylene Glycol is used as an active ingredient in antifreeze and as an anti-icing agent for car windshields, boats and airplane wings. Dipropylene Glycol has a very low freezing point, and acts as a thickening agent, which helps the fluid adhere to surfaces. Dipropylene Glycol is used as a solvent in paints, coatings,
enamels and varnishes. Dipropylene Glycol improves the properties of paints because its slow evaporation time lengthens the time the paint remains suitable for application.

Unsaturated Polyester Resins
The major end use for Dipropylene Glycol is as a raw material in the manufacturing of unsaturated polyester
resins. Markets for unsaturated polyester resins include:
• Residential and commercial construction
• Marine
• Transportation
• Consumer goods
Unsaturated polyester resins are reinforced with fiberglass to form tough, lightweight composite
plastics that can be used in building and vehicle panels, pleasure boats, appliances, bathroom
components, pipes and ducts.

Automotive/Aerospace
Dipropylene Glycol is used as an active ingredient in antifreeze and as an anti-icing agent for car windshields, boats and airplane wings. Dipropylene Glycol has a very low freezing point, and acts as a thickening agent, which helps the fluid adhere to surfaces. Ice gathers on top of the chemical layer, and then can be wiped off with little effort. When a water-glycol mixture freezes, it retains its flowability and does not create added pressure in pipes or vessels. This also makes Dipropylene Glycol an ideal solution for burst protection in pipe and containment systems.
The benefits of using Dipropylene Glycol for these applications include:
• Low freezing point
• Low mammalian toxicity
• Low flammability
• Excellent heat transfer properties
• A high boiling point, low vapor pressure
Dipropylene Glycol is also an excellent choice for the production of polyglycols for use in hydraulic and brake systems to provide lubricity and anti-freezing protection, and to help reduce swelling of rubber
parts.

Paints and coatings
Dipropylene Glycol is used as a solvent in paints, coatings, enamels and varnishes. Dipropylene Glycol improves the properties of paints because its slow evaporation time lengthens the time the paint remains suitable for application.
