Abstract
A coating composition is based on polyvinyl chloride plastisol containing thermoplastic microspheres and is suitable for use as underbody compound for vehicles. The coating composition contains a mixture of expandable and expanded microspheres, in which the expandable microspheres expand at a temperature in the vicinity of the temperature at which the expanded microspheres begin to collapse. The mixture of microspheres solves the problem of a varying density of the coating when the plastisol is gelatinated.
