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&#x2266;&#xd7;x&#x2266;80, 10&#x2266;y&#x3c;95, 0&#x2266;v&#x2266;50, 0&#x2266;w&#x2266;10 and x+y+v+w=100. A single- or double-sided adhesive tape consisting of at least one support and at least one layer of such a pressure-sensitive adhesive therefore likewise has good cohesion and aging resistance properties.

Pressure-sensitive adhesives based on natural rubber and polyacrylates

Hot-melt pressure-sensitive adhesive based one or more non-thermoplastic elastomers, at least comprising 100 parts by mass of the non-thermoplastic elastomer(s), from 1 to 200 parts by mass of one or more tackifying resins, from 1 to 100 parts by mass of one or more reactive phenolic resins whose methylol content is from 1 to 20% by weight, based on the reactive phenolic resin, from 1 to 100 parts by mass of accelerator substances.

Reactive phenolic resins in the preparation of highly viscous self-adhesive compositions

Hot-melt pressure-sensitive adhesive based one or more non-thermoplastic elastomers, at least comprising 100 parts by mass of the non-thermoplastic elastomer(s), from 1 to 200 parts by mass of one or more tackifying resins, and also one or more polyfunctional isocyanates which are free from blocking agent, the hot-melt pressure-sensitive adhesive comprising from 8 mmol to 5 mol of the reactive isocyanate groups of the isocyanate per kilogram of the non-thermoplastic elastomer(s) used.
