tesa® 7140

Flange masking tape in the automotive industry

  • PET layer allows smooth demasking without the tape tearing
  • PVC layer for high paint adhesion to avoid overspray in window flange areas
  • High temperature resistance up to 170°C/1h for most paint shop processes
  • tesa® 7140 PV0 is highly compatible with all relevant e-coats/fillers and window glues.

Product description

tesa® 7140 PV0 consists of a laminate of PVC film with a PET film. It combines the preferred features of both materials: The PVC film ensures high paint adhesion to the backing and increases the flexibility of the tape, while the use of the PET layer results in a high tensile strength. These properties are important in the automotive industry, as they allow the masking of window flange areas prior to paint processes, thus eliminating the need for additional surface treatment steps (such as primer) during the application of the window panes. Instead, the window pane can be directly bonded to the e-coated window flange area.

The high temperature resistance of up to 170°C ensures that the tape works in most oven and baking processes in automotive paint shops. tesa® 7140 PV0 can be applied manually, semi-manually (hand applicators), or completely automatically (robot dispensers).

Application Fields

tesa® 7140 PV0 is suitable for window flange masking in the automotive industry (e.g. windshield, sunroof).
