Epon 828, Technical Grade [25068-38-6]

EPON 828 is an undiluted clear difunctional bisphenol A/epichlorohydrin derived liquid epoxy resin. Poly(bisphenol-A-co-epichlorohydrin) is an epoxy polymer that reacts with a fatty acid to form a cationic polymer. It has a high resistance to thermal expansion and inorganic acids, making it a good sealant. In addition, poly(bisphenol-A-co-epichlorohydrin) is insoluble and not reactive, which makes it resistant to structural analysis. Poly(bisphenol-A-co-epichlorohydrin)'s thermal stability also makes it suitable for use as a boron nitride coating on zirconium oxide.
