ABSTRACT:
Rubber based adhesives containing liquid stereospecific polybutadiene rubber, one or more hardeners or hardener systems, fillers and optionally primers, which contain one or more chemically irreversibly depolymerized solid rubbers of natural or synthetic origin in quantities of from 1.5 to 5% by weight, based on the sum of the constituents, to a process for the production of these low-viscosity rubber-based adhesives by chemically irreversible depolymerization of one or more solid rubbers of natural or synthetic origin, and to the use of these low-viscosity rubber-based adhesives in the bonding of metal components in automotive manufacturing.
