Abstract EN
In this research project, the EPON 828 /Hardener 2512 epoxy resin coating has been prepared at the ambient laboratory temperature with different epoxy/ hardener ratio.
The study of the structural changes in this coating and the determination of its cross-linking degree has been carried out using infrared spectroscopy (FTIR) in the middle range.
The epoxy coating subject of this research and its components have been characterized using various measurement methods, especially the study of hardness evolution, adhesion resistance and tensile properties in terms of time and coating composition.
The chemical resistance of the epoxy coating has been characterized by examining the effects of exposing different coating samples to a number of corrosive chemicals during different time periods.
Results show that the cross-linking degree and hardness of the epoxy coating both increase with the ratio of amine hardener.
When the hardener ratio is of 43% the cross-linking degree of the coating reaches 95% within five days and the hardness achieves the highest degree at that ratio.
With regards to adhesion resistance and tensile strength, highest values were observed when the ratio of amine hardener was close to the ratio (33%).
Regarding chemical resistance, there was no one distinct ratio providing the coating with good chemical resistance against all corrosive tested chemicals.
The results showed that each epoxy/ hardener ratio exhibited good chemical resistance toward one of the corrosive chemicals.
The overall results confirmed that the studied epoxy coating allows an appropriate margin of components percentage variation and consequently a wide margin of physical, mechanical and chemical properties.
