3M 9731

3M 9731 was developed with a high-performance acrylic adhesive on the face side and a silicone adhesive on the liner side of a 1 mil clear PET carrier.
It is excellent for demanding applications where silicone materials must be bonded to a range of substrates.

Adhesive Type: Acrylic/Silicone, Acrylic
Backing (Carrier) Material: Polyester Film, Polyester
Total Tape Thickness without Liner (Imperial):5.5 mils, 2 mil
Total Tape Thickness without Liner (Metric):0.14 mm, 0.05 mm

Combining a silicone-based adhesive and a rubber-based adhesive on a flexible, strong 1 mil clear polyester film (PET) carrier, our 3M™ Double
Coated Tape 9731 is excellent for gaskets and other specialized applications involving silicone parts.
The silicone adhesive provides a good bond to silicone rubber and strong holding power to various silicone surfaces.
The face side features 3M™ Adhesive 350, an acrylic adhesive that provides very high adhesion to a wide variety of materials.
Both adhesives enable the tape to perform effectively across a range of applications, including high-temperature performance, good solvent resistance, very good holding power, and excellent UV resistance.
The thin polyester carrier provides dimensional stability and improved handling with ease of die-cutting and lamination.
Both the 3 mil PET liner and the poly-coated kraft paper release liner provide reliable performance for industrial applications, such as die-cutting and automated dispensers.
The liners also help reduce edge curl and protect the tape from humidity extremes.
