Performance evaluation of different hardener for epoxy resin

Performance evaluation of different hardener for epoxy resin Coatings with outstanding chemical and physical properties can be obtained from two‐pack formulations without stoving. The epoxy resin was cured with different amine‐based compounds, such as polyamide (PA), the aniline copolymer of triethanolamine titanate and aniline formaldehyde.

Abstract

Coatings with outstanding chemical and physical properties can be obtained from two‐pack formulations without stoving. The epoxy resin was cured with different amine‐based compounds, such as polyamide (PA), the aniline copolymer of triethanolamine titanate and aniline formaldehyde. The thermal resistance properties of the cured films were analysed using the thermo‐gravimetric method. This study also examined the effect of coating resistance of 3 per cent sodium chloride solution by means of electrochemical impedance measurements. Coatings that included the epoxy triethanolamine titanate showed superior behaviour, compared to the other two systems tested. This hardener can be recommended instead of using conventional PA and polyamidoamide hardeners for epoxy two‐pack systems that are to be used to protect the steel structures from highly corrosive chemical and marine environments.
