Product information

tesa® 4185

High-temperature fineline tape for design painting in the automotive industry

Product description

tesa® 4185 is a thin and flexible, temperature resistant PVC fineline tape with a natural rubber adhesive and is designed for two-tone car body applications during OEM paint shop processes. The 110 µm thickness helps to give fine and exact color split lines in visible areas, such as the inner side of the car roof frame.

The soft PVC backing of tesa® 4185 allows the tape to be applied on narrow shapes or curves. With a temperature resistance of 160°C/1h, tesa® 4185 can also perfectly withstand most temperatures in automotive paint shops.

Standardized and customized applicators for tesa® 4185 are available to ensure efficient tape application.

Main features:
  • High temperature resistance for inline paint shop processes
  • Thin design for visible edge line applications
  • Good conformability with multidimensional surfaces
  • Residue-free removal
  • Applicators available for high application efficiency

Main applications

tesa® 4185 is suitable for various types of masking applications.

Example applications are:
  • Two-tone painting at high temperatures in automotive paint shops
  • Masking for highly visible edge lines
