It has good water resistance, suitable for low-voltage wire insulation, handling abnormal conditions in the connection, moisture-proof sealing of the ground wire of the high-voltage joint, wrapping and covering of the surface of the winding high-voltage line and irregular joints or valve joints.


Volsun waterproof sealing mastic tape have the following advantages:


  • Operating temperature:-40℃~+85℃

  • Non-corrosive adhesive in the form of flexible tape, clean to use, no waste

  • Provides optimal compliance to help seal multi-conductor cable connections and wire outlets at high voltage

    contacts

  • Sealing grade:IP68

  • Clean the surface of the substrate to be installed before use

  • Cut the product size based on the dimensions of the installation position

  • The environment should be free of large debris or other pollutants to avoid affecting the installation effect

and protective performance of the material

  • The cutting size of the product should be similar to that of the installation position. The deviation should not

be too large
