Cycloaliphatic Epoxy Resins (CER)
Technology
CER Technology
CERs - Different from Standard Bisphenol-A Epoxy Resins like DER 331, EPON 828
Standard Epoxy resins made from Epichlorohydrin and Bisphenol-A
CERs are made by oxidation of Cyclo Olefins with Peracetic Acid
Different from other cycloaliphatic epoxy resins like Glycidyl Esters of Pthalic Acids (Huntsman CY 184) and Hydrogenated Bis A Epoxy Resins (CVC Epalloy 5000 and Hexion Epon 1110)
Technology
Standard Epoxy Resin : Epichlorohydrin + Bisphenol-A
Std. Epoxy Resin Epichlorohydrin (DER 331, EPON 828) Bisphenol-A
Technology
Cycloaliphatic Epoxy Resin : Cyclo Olefin + Peracetic Acid
GPE-221 GPE-221 Cyclo Olefin Peracetic Acid
