<p>Self-adhesive protective films for surface protection applications on painted vehicles or vehicle components, comprising a single- or multi-layered, in particular polyolefinic support layer and a self-adhesive layer are characterised in that the self-adhesive agent contains 100 parts of a component (A), comprising a vinylacetate copolymer or a mixture of several vinylacetate copolymers of various molecular weights with a vinyl acetate content of 60 to 75 wt. % and a maximum for the dissipation factor tan δ, as determined by DMTA at an angular frequency φ = 1 rad/s, of < 0 °C, 5 to 80 parts of a component (B), comprising a vinyl acetate copolymer or a mixture of several vinyl acetate copolymers of various molecular weights with a vinyl acetate content of 75 to 95 wt. % and a maximum for the dissipation factor tan δ, as determined by DMTA at an angular frequency φ = 1 rad/s, of ≥ -5 °C and 5 to 80 parts of a component (C), comprising a vinyl acetate copolymer or a mixture of several vinyl acetate copolymers of various molecular weights with a vinyl acetate content of ≤ 70 wt. %, where the vinyl acetate content is also at least 5 wt. % below the vinyl acetate content of component (A).</p> |
