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.
