tesa® Professional 4600 Xtreme Conditions

Self-welding silicon tape for an instant hermetic seal


Product description

tesa® 4600 is a strong self-amalgamating tape made from silicone which bonds without adhesive. It is applied with tension by wrapping the tape around itself. The bondage of tesa® 4600 on its own backing creates a water tight, permanent sealing. No drying time is required. Its flexible material can be applied smoothly on any kind of surface, including wet or warm, dirty or oily. Xtreme Conditions can be used also for temporary applications leaving no residues after removal. The tape can even be applied under water. Due to its silicone backing the tape has an excellent resistance to various chemical substances, oils, acids, solvents, salt water, UV radiation and extreme temperatures.

tesa® 4600 for professional distribution and standard applications comes with a thickness of 500µm and with a roll length of 3m. It is available in transparent and black and always comes with a liner.

  • Stretch the tape to at least double its normal length. Apply it tight on the surface and overlap it tight around itself.
  • To serve the best purpose for standard electrical applications wrap 3 time with 100% overlapping.
  • For high pressure leaks (e.g. sealing of pipes) the tape should be stretched very tight and several layers should be used. Depending on the leak and pipe material the tape can withstand a pressure of 12 bar max. Please use max. 4 layers with approx. 100mm tape on both sides of the damaged pipe.
  • Due to the self-fusing process, after applying the tape on itself, a permanent bond is created. Therefore, the tape can be used once.
  • Please be aware: Xtreme Condition is not compatible with drinking water
