tesa® 51108

High-temperature PET masking film for automotive paint jobs

Product description

tesa® 51108 combines a polyester backing and a thermosetting adhesive to achieve the optimal performance for high-quality automotive paint jobs. The temperature resistance of up to 150°C(302°F)/1h and the high tensile strength provide an ideal usage for two-tone painting on car bodies at the automotive OEM or on bumpers at OES, especially if long straight lines are required. Due to the low thickness of 54 µm/2.1 mils, the tape creates extra sharp paint lines.

Standardized and customized applicators for tesa® 51108 are available to ensure efficient tape application.

Main features:
  • Thin PET film for straight and thin paint lines
  • High tensile strength for easy demasking without the tape tearing
  • Residue-free removal up to 150°C(302°F)/1h

Main applications

tesa® 51108 is suitable for various types of masking applications.

Example applications are:
  • Two-tone painting at temperatures up to 150°C(302°F)/1h
  • Masking of straight lines on car bodies or bumpers

To ensure the highest performance possible, our aim is to fully understand your application (including the substrates involved) in order to provide the right product recommendation.
