Tacky mouldings, in particular sealant profiles, comprise plastisols based on PVC and/or polymeric methacrylates and also contain ethylene-vinyl acetate copolymers having different vinyl acetate contents, fillers and pigments, plasticisers, adhesive resins and polyisobutylene. Tacky mouldings which meet the demands of automotive and bodywork production, i.e. have sufficient low- temperature adhesion to, for example, EC-primed metal sheeting, good adhesion at the elevated temperatures in the curing process and adequate chemical stability at such high temperatures, are obtained by accurate balancing of the amounts of the individual constituents. The mouldings can also be produced by room-temperature processing. |
