3M™ 1181 Tape consists of a 1-ounce deadsoft copper foil backing and a unique electrically conductive pressure-sensitive acrylic adhesive.

• Copper foil with conductive acrylic adhesive
• Deadsoft 1-ounce copper foil backing
• Supplied on a removable liner for easy handling and diecutting
• The copper foil backing is solderable and resists oxidation and discoloration
• Common uses include grounding and EMI shielding in equipment, components, shielded rooms, etc.

• Extreme Hot and cold temperature versatility. 3M foil tape works in temperatures to which other tapes would diminish. Performing in cold conditions allows this 3M tape to be a market leader, as other tapes see the adhesive harden and begin to lose sticking strength. On the contrary, extreme heat can melt adhesives of tapes, but not the 3M foil tape making it versatile for most applications.

• An Acrylic Adhesive backing. This 3M Aluminium foil tape is coated in a superior acrylic adhesive, which works well in extreme cold and heat conditions. This matters when comparing to most duct tapes that are made with a rubber adhesive. This is then known to delaminate from its backing in these extreme conditions. Other adhesives can offer greater resistance but will lack mechanical strength, poor ageing resistance and UV light.

• Longevity of foil tape. Within the construction industry, the use of pressure sensitive tapes is often used in hard to reach areas. This means they can't be easily replaced or repaired. The acrylic adhesive on the 3M aluminium foil tape offers better cohesion, adhesion and thermal properties.

EMI/RFI Shielding Tapes

When using these tapes galvanic compatibility should be taken into account.
