1. Description
D-678 Neopentyl glycol diglycidyl ether, neopentyl glycol by dehydration
reaction with epichlorohydrin formed, non-irritating odor, boiling point
greater than 150 ℃, molecules containing two epoxy groups, take part in
curing reaction to form a chain and mesh. Dilution effect with the
single-ether considerable. However, after curing resin tensile strength,
anti-bending strength, compressive strength, impact strength and other
mechanical properties as well as the adaptation period are better than
single-ether resin curing. Epoxy resin as a reactive diluent in the same
temperature under the conditions of epoxy resin and curing agent to
reduce the reaction activity. Are widely used in flooring, solvent-free
coatings, laminates, adhesives and transparent epoxy casting system and
the electrical ring forming oxygen system. As a cellulose fiber
finishing agent can increase flexibility, fastness, alkali resistance,
dyeability, etc., can be used for cotton, hemp, wool silk and other
fabric finishing. Can improve the tensile strength fibers.

5. Use
Mainly used as a reactive diluent in epoxy resin. Dilution effect of
epoxy resin, volatile low, on the curing properties of the impact of
small objects, mainly for Epoxy Floor Coatings, concrete repair and
so on. .
4. The amount of
General amount of epoxy resin 15 ~ 35% (weight ratio). Because of
D-678 contains epoxy groups can react with the curing agent, which
when used must be a corresponding increase in the amount of curing
agent.
5. Packaging and storage
5kg plastic pail or 180Kg iron drum packing. Sealed to preserve.
