ANTI-RUST PRESSURE-SENSITIVE ADHESIVE FILM FOR AUTOMOTIVE BRAKE DISK

摘要

An anti-rust pressure-sensitive adhesive film for automotive brake disks which comprises a surface base film having a tensile modulus of 30-200 MPa, yield strength of 5 N/15 mm or lower, and yield elongation of 7.0% or less and a pressure-sensitive adhesive layer disposed on the back side of the surface base film. This pressure-sensitive adhesive film has excellent conformability and can be easily applied/bonded to a wheel surface of a three-dimensionally complicated shape or wheel surface having thinned spokes. After application to an automotive wheel, the adhesive film is less apt to peel off and highly prevents the automotive brake disk from rusting.
