Abstract
An aspartic ester was synthesized from 4,4'-methylenebis (2-methylcyclohexylamine), diethyl maleate and mono-epoxy. The method of synthesis, properties and structure of this material has been studied and published [1]. Aspartic ester mixed with additives to produce a 2-component polyurea coating system. Polyurea coating from aspartic ester cured by Desmodur N 3600 undergoes accelerated tests of environmental degradation by salt-fog and Q-sun. The metal protection capacity of the polyurea coating was evaluated through image, mechanical properties and electrochemical impedance before and after environmental acceleration. Keywords. Polyurea, aspartic ester, metal coating, coating protection
