Product description

tesa® 4831 is a silicone-free masking tape made of a PET/non-woven backing and an acrylic adhesive. It is especially designed for highly demanding applications such as prebond masking, composite manufacturing and metal sandwich construction.
Thanks to its robust PET/non-woven backing and acrylic adhesive, it can be exposed to high pressure and temperatures of up to 180 °C. It is silicone-free, which makes a contamination of the surfaces with silicone adhesive impossible. Subsequent process steps such as window gluing or coating can therefore be carried out with maximum reliability avoiding time consuming cleaning.

Application Fields

  • Prebond masking for subsequent bonding applications, e.g. gluing of windows.
  • Fixation/masking of parts during composite or metal sandwich construction.
  • Also ideal for 2-tone painting providing precise paint edges.
  • Powder coating
