摘要:
A pressure-sensitive adhesive consisting of a homogeneous mixture of at least one natural rubber component and at least one polyacrylate component displays significantly improved properties in cohesion and aging and weathering resistance compared to the individual components. Particularly good properties are achieved when the adhesive contains x% by weight of at least one natural rubber component, y% by weight of at least one polyacrylate component, v% by weight of at least one adhesive resin component and w% by weight of additives, where 10≦×x≦80, 10≦y

摘要:
Adhesive, more particularly pressure-sensitive adhesive, which comprises expanded microballoons, the bond strength of the adhesive comprising the expanded microballoons being reduced by not more than 30%, preferably not more than 20%, more preferably 10%, in comparison to the bond strength of an adhesive of identical coatweight and formula which has been defoamed by the destruction of the voids produced by the expanded microballoons.
