ABSTRACT:
The thermo-setting reaction adhesive present as a mono-component system contains as its essential components respectively at least a) one unsaturated scaffold polymer based on a non-cross-linked elastomer in a share of 5 to 90% by weight, b) one unsaturated polyester in a share of 5 to 90% by weight, c) one unsaturated cross-linking agent in a share of 0.1 to 50% by weight, d) one setting catalyst which provides radicals with an activation temperature of 60.degree. to 300.degree. C. in a share of 0.2 to 6% by weight and f) optionally other additives. The adhesive is distinguished by high storage stability and high adhesive strength with a short cross-linking time and it is particularly suitable for bonding thermo-shrinking molded parts.
