Abstract
Self-adhesive protective film for the exterior of painted vehicles, especially cars, characterized in that the backing of the protective film is a film, the UV permeability in the range from 290 to 400 nm is below 1%, the bond strength on steel is between 0.2 and 2.8 N/cm and the adhesive composition consists of a copolymer comprising at least two different α-olefins having 2 to 12 carbon atoms and at least one further comonomer, no α-olefin having a proportion of 75 mol-% or more in the adhesive composition as a whole.
Claims15
A method for protecting the paint finish of a vehicle or for protecting a painted vehicle component against soiling and damage during assembly, transportation or storage, said method comprising applying to said vehicle or vehicle component a self-adhesive protective film, said self-adhesive protective film comprising:
- a) a backing film;
- and
- b) an adhesive composition coated on said backing film, wherein the adhesive composition comprises a copolymer of at least two different α-olefins having 2 to 12 carbon atoms and at least one further comonomer, said adhesive composition not containing 75 mol-% or more of any single α-olefin;
- wherein
- the UV permeability of the self-adhesive protective film in the range from 290 to 400 nm is below 1%;
- and
- the bond strength of the self-adhesive protective film on steel is between 0.2 and 2.8 N/cm.
