Specific advantages of the double-sided tapes are:
- homogeneous
distribution of mechanical loads
- dampen vibrations and noise
- absorb impact
- join dissimilar materials
- resist
plasticizer migration, avoiding stress cracking problems
- good
aesthetics / no special requirements to hide the bond
- economic
assembly / minimal application training / no investment in major equipment
- low weight, no heavy bolts and nuts
- differences in thermal
expansion of components can be compensated in a thick adhesive layer
-
heat sensitive constructions or materials, which welding would distort or
destroy, can be joined.
Potential limitations are:
- stress cracking or crazing caused by the
adhesive
- reproducibility/process control
- disassembly.
Adhesive transfer tape consists of a pressure-sensitive adhesive pre-applied
to a special release liner. The tape is simply applied to a surface and the
liner is peeled off. This leaves a clean, dry strip of acrylic adhesive for
joining lightweight materials.
Pressure-sensitive tapes require a clean surface for optimal strength.
