Tape technologies: PSA constructions
The various PSA tape components are combined and supplied in the following basic constructions:
Transfer Tape
A film of unsupported adhesive is coated directly onto a siliconized release liner. The release liner is coated with silicone on both sides to ensure that the tape unwinds easily and can be laminated to various substrates. Double linered transfer tape constructions may be offered. Offers superior conformability Ideal for nameplate mounting and foam bonding
Single Coated
The adhesive is coated on one side of a carrier. A release liner coated on one side with silicone protects the adhesive. Potential label stock Foil insulation tapes
Double Coated
The adhesive is coated on both sides of a carrier material. This construction is provided on a liner coated on both sides with silicone. Double linered, double coated constructions may be offered. Offers improved internal strength Greater dimensional stability, easier converting Easily slit into narrow rolls Adds support to otherwise stretchy materials
Selfwound
The adhesive is coated on one side of a carrier. The other side of the carrier is generally coated with silicone to enable the tape to unwind easily. Provides wrap around sealing Acts as closure system Potential label stock Can provide moisture vapor barrier
Heat-Activated
A heat-activated film laminated to a pressure- sensitive adhesive on a release liner coated on both sides with silicone. Designed for difficult to bond materials Ideal for shipping pads, non-slip step pads and certain sound damping materials
