Detailed Description

4,4'-Bis(2,3-epoxypropoxy)-3,3',5,5'-tetramethylbiphenyl
Synonym:3, 3’,5, 5’-Tetramethyl-4,4’-di(2,3-epoxypropanoxy)-bibenzene,TMDE
CAS NO : 85954-11-6
Molecular Formular:C22H26O4
Product Introduction:
TMDE is a two glycidyl ether type epoxy resin which has the structure of biphenyl. It has the good color and transparency.Compare to the common epoxy resin,it has the good heat-resistance and mechanical properties,high epoxy value186-197g/eq, total chlorine content lower than 1500ppm.TMDE is a new type of high performance-price ratio epoxy resin.
1、 With rigid backbone,has the high tg.
2、 Crystalline solid epoxy resin
3、 Low stress, high adhesive performance
4、 Methylcontent,has the low hygroscopicity.
5、 Low molten viscosity,0.1-0.2 p at 150℃,high highfluidity.
