Organic coatings based on new Schiff base epoxy resins

• We developed new Schiff base epoxy resins.
• We determined physical, mechanical and thermal properties of coatings based on new epoxy resins.
• New coatings had very good properties in comparison with coatings based on commercial epoxy resin

New Schiff base epoxy resins were developed and used as a component of binder of new organic coatings. The structure of synthesised compounds was confirmed by means of spectroscopic (NMR) and spectrometric (ESI-MS) techniques. Synthesised epoxy resins were cured with selected polyamine at room temperature. Physical, mechanical and thermal properties of coatings based on new epoxy resins were determined. Results were compared with those for one selected commercial epoxy resin.The results of investigations prove that coatings have good elasticity, impact resistance and its adhesion to the substrate is comparable, or even better than that of coatings based on the widely used commercial epoxy resin. An additional property this coating demonstrates is its good thermokinetic properties.
