What is Neopentyl glycol diglycidyl ether ?
Chemical properties
colourless liquid
The Uses of Neopentyl glycol diglycidyl ether
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.
The Uses of Neopentyl glycol diglycidyl ether
NGDE can be used in the synthesis of epoxy polymers for the development of shape memory polymers. It can also be used in the photopolymerization of cationic polymers.
The Uses of Neopentyl glycol diglycidyl ether
Neopentyl Glycol Diglycidyl Ether is used in preparation of aqueous Epoxy curing agents for orange peel-like leveling coatings.
Production Methods
The ether is made by condensing neopentyl glycol with epichlorohydrin followed by dehydrochlorination with caustic.
General Description
Clear liquid.
Air & Water Reactions
Slightly soluble in water.
Reactivity Profile
Neopentyl glycol diglycidyl ether 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.
Fire Hazard
Neopentyl glycol diglycidyl ether is combustible.
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.
