Abstract:
A description is given of a nonaqueous sound deadener composition comprising (a) a nonpulverulent, solvent-free polyacrylate binder having a K value in the range from 10 to 35, measured as a 1% strength solution in tetrahydrofuran; and (b) inorganic fillers. Also described is a method for damping oscillations or vibrations of components of vehicles and machines, using the sound deadener composition of the invention.
