E208 Polypropylenglycol Diglycidyl
Ⅰ Chemical formula and molecular weight
● Chemical Name: E208 Polypropylenglycol diglycidyl , PPGDGE
● Molecular weight: O(CH2CH) CH2O[CH2CH(CH3)O]nCH2(CHCH2)O
● CAS No.: 26142-30-3
Ⅱ Properties and application
● E280 is a difunctional reactive diluents for epoxy resin with good elasticity, give good
flexibility and elongation for epoxy resin, and improve it's impact strength.
● E208 can be made to various epoxy resin refractory castables, solvent free epoxy glue,
soaking glue, trickle impregnating glue and adhensive. It is a good epoxy resin diluents for
medium and large dry type transformers, transformer high-voltage switch components, and glue
for micro-motor,capacitors and other electronic component. It also improve flexibility of regular
epoxy coatings (flooring, anti-corrosion, potting materials and other fields).
● Main Feature
1. A good epoxy resin diluent, miscible with fat epoxy resin by low viscosity at room
temperature.
2. Greatly improve impact strength, thermal shock resistance and curing epoxy brittle crack.
3. Involved in curing reaction of epoxy resin, molecular structures has pliability fat long chain,
can freely rotate and be elastic
4. High boiling point, not volatile, toxic irritant-free, safe use.
