Modified Schiff base epoxy resins
All used Schiff bases are the derivatives of 2-hydroxybenzaldehyde. Synthesised epoxy resins were used as a component of binder of new organic coatings. Xylene-based solution of polyamide based on dimerised fatty acid and polyamines and poly(oxypropylene diamine) were used as a hardener for the synthesised and commercial epoxy resins at room temperatures.
New epoxy resins with good elasticity and impact resistance
Physical and mechanical 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 based on new epoxy resins have good elasticity and impact resistance. And their adhesion to the substrate is comparable or even better than that of coatings based on the widely used commercial epoxy resin.
