Beschreibung
Zusammenfassung:	An epoxy resin bonding composition containing two different epoxy resin as a liquid admixture, a curing agent and a polyamide powder is disclosed. The bonding composition may be used, for example, to bond a ferrite magnetic to a motor yoke. One of the epoxy resins is an unmodified glycidyl ether of bisphenol A, bisphenol F or bisphenol AD. The other epoxy resin is an urethane-modified or glycol-modified glycidyl ether of bisphenol A, bisphenol F or bisphenol AD. The polyamide powder has an average particle size of 150 mu m or less and a melting of at least 170 DEG C. and is present in an amount 1-50 parts by weight per 100 parts by weight of liquid epoxy resin admixture.
