3M 3302 vs. 1170: Which Tape Fits Your Project? Compare conductive foil tapes, roll lengths and ordering options for your next shielding project.
Could You Save Approximately 62%?
Based on historical NBS prices for 2-inch tape, 3M 3302 cost about 62% less per linear foot than 3M 1170. This is illustrative, not a current quote. Actual savings depend on updated prices, quantities and requirements.
Both products can be valid options when they meet your project specifications. Verify requirements before substituting, especially on SCIF projects.
3M 1170 and 3M 3302 are aluminum foil tapes with conductive acrylic adhesive for EMI/RFI shielding applications. Choose the tape specified for the assembly, then compare width, roll length, case quantity and current product documentation.
Compare Cost per Foot
A 108-foot roll of 3M 3302 provides twice the length of a 54-foot roll of 3M 1170. Compare the same width using price per roll divided by roll length. Case sizes differ, so comparing case prices alone can be misleading. Ask us for current project pricing and a side-by-side cost comparison.
Compare the Product Data Before Specifying
Review electrical contact properties, backing and adhesive construction, surface preparation, storage conditions and application guidance in each current technical data sheet. A tape's laboratory result is not a rating for every field seam or completed enclosure.
Compare shielding results only when the test method, frequency range and configuration are compatible. Do not select tape solely by a quoted average dB value.
Using Conductive Tape with ULTRA NT SCIF Barrier
The ULTRA NT guide lists 3M 1170 and 3302 as proposed conductive seam-tape options, subject to project approval. Follow the approved overlap, tape-width and interface details in the SCIF barrier installation instructions. Press the specified tape firmly over the full seam contact area.
Non-conductive adhesive tape cannot replace the specified conductive seam bond.
