What type of 3M? Thin Bonding Tape should I use for my application?

When choosing a suitable adhesive tape, the adhesive is not the only important consideration. In this article you can learn more about the different product constructions of Thin Bonding tapes.

3M? Adhesive Transfer Tapes

• Thickness: 25 – 250 μm
• Without (intermediate) carrier
• High flexibility and conformability
• Compensates for surface roughness very effectively

• Higher temperature resistance than double coated tapes
• Automated processing recommended for large areas
• More difficult to handle and to die-cut (edge picking) than double coated tapes (thread reinforced adhesive transfer tapes are available for easier handling)

3M? Double Coated Tapes

• Thickness: 50 – 250 μm
• With (intermediate) carrier
• Lower flexibility and conformability than adhesive transfer tape
• Compensates for surface roughness less effectively than adhesive transfer tape
• Carrier limits temperature resistance

• Increased internal stability thanks to carrier
• Easier to handle and to die-cut and better dispensability
• Different adhesives on both sides possible
• Levelwound rolls possible

3M? Spacers

• Thickness: 80 μm – 350 μm
• With (intermediate) carrier
• Primarily as sheetstock, but also available as rollstock
• Liners on both sides

• Different liner thicknesses available
• For use in membrane switches (spacer function)
• High dimensional stability and rigidity
• Good die-cutting and processing properties
