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:
A process is presented for the preparation of a high-cohesion non-thermoplastic pressure-sensitive adhesive (PSA) on the basis of elastomers, in which neither a solvent nor thermoplastic additives are used and yet thermal breakdown during compounding is kept low. This is achieved through the addition of a vaporizable process agent which is introduced into the adhesive after the constituents have been premixed and which undergoes flash vaporization therein, thereby quenching the adhesive. Furthermore, the use of water to cool the adhesive is proposed, and the high-cohesion PSA thus produced, and also a pressure-sensitive adhesive tape with an adhesive of this kind, are presented.
