Product Handling

The appropriate length of 3M™ Scotch-Seal™ Mastic Tape 2229 can easily be cut off the

roll by using a sharp knife or suitable protected razor blade. It can be applied in layers or

can easily be molded into the desired shape.

Note: Since a large number of different semi-conductive jacketing materials are currently

available, the user is urged to test the compatibility of 2229 mastic tape with the semi-

conductive jacketing material being used.
