ABSTRACT:
The invention is an adhesive, in particular, for components that operate with surface acoustic waves, including a polymer matrix filled with mineral filler particles. The filler is selected from non-conductive or semi-conductive materials and is contained in the adhesive in such a proportion that the total density of the adhesive when cured is greater than 2000 kg/m3.
