Repair patch for an elastomer component with an improved connection layer

Abstract

A repair patch for an elastomeric element, particularly for a vehicle tire, use thereof and method for bonding a repair patch to an elastomeric element. The repair patch (1) comprises: a top layer (10), a bonding layer (30) for covering a wall (80) of the elastomeric element (40), and at least one intermediate layer (20) arranged between the bonding layer (30) and the top layer (10), wherein prior to vulcanization with the elastomeric element (40), the bonding layer (30) has a first and a second natural rubber component, wherein the first natural rubber component has a lower molecular weight Mw than the second natural rubber component, such that a mixture of the first and second natural rubber components has a bimodal molecular weight distribution.
