摘要：
Cathodically depositable paint binders based on epoxy resin/amine adducts modified with diamine bridges which carry longer-chained substituents are described. The diamine bridges are the reaction products of diprimary amines and mono- and diepoxy compounds. The modified epoxy resin/amine adducts have low viscosities and low glass transition temperatures in spite of their high molecular weights. The stoved films, even with higher film thickness, have flawless surfaces and excellent mechanical properties.
