Abstract

In this study, stabilization of plastisol of automotive underbody coating containing 1%, 3% and 5% of OMMT in the presence of Nano ZnO were prepared. Migration of plasticizer (DOP) used, in all of the samples before curing and aging were studied by incubation for 45 days. The best condition with minimum level of migration of the plasticizer was obtained for Nano composite containing 5% of Nano clay. Modification of thermal stability of the samples being another object of the present work were studied under similar curing conditions. Minimum thermal degradation was occurred with Nano composite containing 5% of Nano clay. Surface properties of Nano composite after aging for 6 months and curing of plastisols were studied by scanning electron microscopy (SEM). The comparison of pure Nano clay with Nano composites containing (1%, 3% and 5%) Nano clay were studied by X-Ray Diffraction (XRD).
