11. LS-207(217、227) Polypropylene Glycol Diglycidyl Ether
11. 1. Product Introduction
Chemical Name: Polypropylene Glycol Diglycidyl Ether (PPGGE)
Structural Formula: O(CHCH2) CH2O[CH2CH(CH3)O]nCH2(CHCH2)O
CAS NO.:26142-30-3
Specific Gravity:1.13-1.15
Appearance& Character: Colorless to slight yellow transparent Liquid. It can be miscible with an epoxy resin, a low viscosity at room temperature is a good epoxy diluent; high boiling point, non-volatile, non-toxic and non-irritating to use safety; participate in the curing reaction of the epoxy resin, with flexible aliphatic long chain in molecular structure, can rotate freely and flexible, added to the epoxy resin formulations can greatly improve its impact strength and cold impact resistance, to improve the embrittlement of the cured epoxy defects.

11.3.Applications
Dual functionality of epoxy resin active diluent, good flexibility, can be used for the preparation of a variety of epoxy resin casting materials, solvent-free coatings, Impregnation glue, and drop cord glue and adhesive, widely used in large and medium-sized dry-type transformers, transformer high-voltage switching components, micro-motors, capacitors and other electronic components manufacturing; also is the main components of the automotive electronic paint.
11.4. Packing
Packed in 25 kg/plastic drums or 200 kg/plastic drum or iron drum
11.5. Attention in storage
11.5.1. Storage and transportation must conform to basic requirements of normal chemicals.
11.5.2. Stored in a cool, dark, dry and well ventilated area for one year. Keep away from ignition sources, heat and flame and sunlight.
11.5.3.It is necessary to maintain insulated (tightly seal) after use, in order to avoid negative influence arousing from moisture absorption.
11.5.4. This product irritates to the skin and eyes. If contact with skin, wash with
soap; if contact with eyes, rinse with plenty of water.
