3M Scotch 70 Self Fusing Silicone Tape is a high quality, high temperature resistant grade of silicone self-amalgamating tape designed for sealing, insulating and bundling. This tape is manufactured from inorganic rubber and comes with an easy-release liner that makes installation very easy. This tape is grey in colour, is 0.3mm thick and withstands continuous exposure to temperatures up to 180°C.

3M Scotch 70 Self Fusing Silicone Tape has excellent dielectric strength and creates an effective seal. It sticks only to itself and this adhesion is pretty-much instantaneous which makes installation very easy. The tape itself is highly conformable and can be wrapped and applied around bends and irregular shaped objects.

Applications for 3M Scotch 70 Silicone Tape

  • Protective overwrap for terminations on high voltage cables
  • Primary insulation for medium and low voltage cables
  • Base layer for re-entry into connections
  • Sealing and protecting cable and lead connections


Will this stick to other things?

No. 3M Scotch 70 is designed to only stick to itself. To prevent unwanted premature adhesion each roll is supplied with an easy to remove liner that should be taken off as you apply the tape. 

Are other colours available?

Not of this particular grade. 3M Scotch 70 is only available in grey.
