"Mixture, construction of vibration damping of forced layer, composite vibration damping, Bidirectional Construction of vibration damping layer forced.Pressure sensitive adhesive coated article, article coated with release, and processes to produce a mixture and to produce a pressure sensitive adhesive tape.A mixture is provided comprising (a) at least one of a thermoplastic elastomer, a thermoplastic elastomeric not, an elastomeric thermal fixed, and mixtures of these.Excluding the fluid polidiorganossiloxanos, and (b) a polymer having units of polidiorganossiloxano soft, hard drives poliisocianato residue.Optionally the soft units and / or hard polyamine organic end groups.The residue and the residue poliisocianato hard hard polyamine comprise less than 50% in weight of the component containing polidiorganossiloxano urea.The residue of poliisocianato is poliisocianato devoid of groups of - NCO, and the residue of the polyamine polyamine is devoid of groups - NH ~ 2 ~.The residue of poliisocianato is linked to the residue of polyamine by the joints of urea. The end groups are non functional groups or functional groups.The component containing polidiorganossiloxano urea may be reactive under conditions of free radicals or curing by moisture.The mixture may also optionally contain materials of tackiness, free radical initiator, cross-linking agents, curing catalysts and non reactive additives such as fillers,Pigments, stabilizers, antioxidants, flame retardants, plasticizers, compatibilizadores and others.
