Abstract

Sprayable low-viscosity rubber damping compounds based on liquid rubbers or elastomers and vulcanization agents, which contain small quantities of structure-reinforcing fiber fillers, are notable for the absence of previously usual solid rubbers and have a very low viscosity in the application state. Acoustic compounds of this kind are sprayable with the aid of fully automatic application systems, and are preferably processed at the basic body stage in vehicle construction.
