Chemical Name: Dipropylene Glycol
Trade Name: KEDPG
Introduction
Dipropylene glycol (KEDPG) is a derivative of propylene oxide (PO) and is produced in a two-step process. The first step is the reaction of PO with water results in a mixture of MPG and KEDPG and the second step is the distillation and purification of the mixture into its two separate components.
General Applications
The major end use for KEMPG is as a raw material in the manufacturing of unsaturated polyester resins. KEMPG is used as an active ingredient in antifreeze and as an anti-icing agent for car windshields, boats and airplane wings. KEMPG has a very low freezing point, and acts as a thickening agent, which helps the fluid adhere to surfaces. KEMPG is used as a solvent in paints, coatings,
enamels and varnishes. KEMPG 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 KEMPG 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
KEMPG is used as an active ingredient in antifreeze and as an anti-icing agent for car windshields, boats and airplane wings. MPG 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 MPG an ideal solution for burst protection in pipe and containment systems.
The benefits of using MPG for these applications include:
• Low freezing point
• Low mammalian toxicity
• Low flammability
• Excellent heat transfer properties
• A high boiling point, low vapor pressure
KEMPG 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
KEMPG is used as a solvent in paints, coatings, enamels and varnishes. MPG improves the properties of paints because its slow evaporation time lengthens the time the paint remains suitable for application.
