The thermal analysed results show that in the presence of the recycling<br /> polyurethane, the thermal degradation is not changed in comparison with the orginal PU alone.<br /> Corrosion protection of the PU coating containing the recycling PU was evaluated by<br /> electrochemical impedance measurements. It was found that the properties of protection depends<br /> on the recycling PU content. With 5% content of recycling PU gave the result relatively with the<br /> orginal PU alone. In addition, the adherent measurements show the improvement in presence of<br /> the recycling PU. This result shows the possibility of apphication recycling PU in the protection<br /> anti-corrosion field.<br /> <br /> <br /> I - Më ®Çu II - thùc nghiÖm<br /> <br /> Trong nh÷ng n¨m gÇn ®©y, viÖc t¸i sö dông 1.
