General Description
Clear liquid.
Reactivity Profile
NEOPENTYL GLYCOL DIGLYCIDYL ETHER(17557-23-2) is a ether-alcohol derivative. The ether being relatively unreactive. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert alcohols to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.
Air & Water Reactions
Slightly soluble in water.
Fire Hazard
NEOPENTYL GLYCOL DIGLYCIDYL ETHER is combustible.
Chemical Properties
colourless liquid
Uses
Neopentyl Glycol Diglycidyl Ether is used in preparation of aqueous Epoxy curing agents for orange peel-like leveling coatings.
Uses
Thismay be used as a bifunctional reactive diluent
for viscosity reduction of resins with minimum change
in cured resin properties and to allow increased filler
incorporation.
Production Methods
The ether is made by condensing neopentyl glycol with
epichlorohydrin followed by dehydrochlorination with
caustic.
Carcinogenicity
A 2 year dermal carcinogenicity
study of NPGDGE in C3H mice was conducted at dose levels
of 0.94, 1.87, and 3.75 mg/mouse . Skin tumor incidences
were 10/50, 6/50, and 0/50 at 3.75, 1.87, and 0.94 mg/
mouse; no tumors occurred in the 300 acetone-treated controls.
Tumor potency was calculated to be 1/700th that of
benzo[a]pyrene, which was tested concurrently.
Toxics Screening Level
Due to a lack of available toxicity data, the screening level for Neopentyl glycol diglycidyl ether is being set at 0.1 μg/m3 with annual averaging.
