non-aqueous sound damping composition, use of a sound damping composition, method for damping oscillations or vibrations, and substrate;

摘要

The invention relates to a non-aqueous sound damping composition comprising (a) a non-powdery polyacrylate binder having a k-value in the range 10 to 35, measured as a concentration of 1% solution in tetrahydrofuran; (b) inorganic fillers; and a free radically polymerizable compound comprising at least one free radically polymerizable c-c double bond and has a boiling point at normal pressure greater than 160 ° c. The invention also relates to a method for damping oscillations or vibrations in vehicle and machinery components using the sound damping composition according to the invention.
