Neopentane Glycol Diglycidyl Ether (YF-681)
1. Description:
Chemical name: 1,3-bis(2,3-epoxypropoxy)-2,2-dimethylpropane
CAS Number: 17557-23-2
EC Number: 241-536-7
Molecular formula:C11H20O4
Molecular weight：216
Specific gravitiy:1.04
Flash point:>110℃
Its molecular contains two epoxy groups which can take part in curing reaction of epoxy resin when curing, and form chain and net conformation, although the diluent effect of YF-681 is as good as that of single glycidyl ether, the performance of its cured epoxy such as compressive strength, flexural strength, tensile strength, impact strength and adaptive time is better than that of single glycidyl ether.

3. Application:
- Good wet-keeping, low toxic.
- epoxy resin active diluent, epoxy embedding material, casting material/adhesive, floor material , non-solvent coating, adhesives,
- Used as fibrin treating agent to enhance its flexible, toughness, chromaticity, anti- alkalescence.
- Used as textile treating agent of cotton or hemp or silk to enhance its tensile strength.
- Used in diluent and tougheness improvement, winding-forming.
- Dosage: In general, YF-681 should be 15-35% of Epoxy Resin in weight. YF-681 contains epoxy group which can neutralize curing agent, so it is necessary to add the quantity of curing agent in course of using.
4. Packing:
- Packed in 20 kg/barrel or 200 kg/barrel.
- Storage and transportation must conform to basic requirements of normal chemicals.
- Store in a cool, dry and well ventilated area. Keep away from ignition sources, heat and flame and sunlight.
- It is necessary to maintain insulated (tightly seal) after use, in order to avoid negative influence arousing from moisture absorption.
