illbruck TN573 Sealing Tape P275

TN573 Usage / Purpose
illbruck TN573 is a 1 mm thick PVC foam tape which can be used in narrow gap widths, to provide an effective weather seal even with only a low level of compression.

Key Benefits

  • Excellent insulation performance against shock, vibration and movement
  • Provides an effective weather seal against wind and rain, even under minimal levels of compression
  • Provides a barrier to thermal bridging, galvanic corrosion and acoustic transmission

– Ensure bonding surfaces are free from irregularities and loose particles which may impair adhesion.
– Dust, dirt and grease can be removed using AT115 Solvent Cleaner. Where substrates are sensitive to solvent attack, clean with warm water and allow to dry.
– The substrate must always be dry before application of the tape.

– The exposed adhesive face should be unwound gradually, and carefully located onto the surface of the substrate. Care must be taken to avoid compressing or stretching the tape during location – this could induce peeling forces and cause the tape to lift from the substrate.
– Once the tape has been positioned then apply even pressure throughout the length using a roller, starting at the centre and moving to each end to avoid stretching.
– With double sided tapes the protective release film is not removed until immediately prior to joint assembly.
– The assembly must provide sufficient force to compress the tape by 20% of original thickness for security applications and 30% if weatherseal performance is required. Over compression should be avoided.
– Joints may be made by mitring corners or butting the tape ends tightly together. In all cases the tapes should be cleanly cut at slightly longer length than required to ensure compression of the joining faces, and formation of a tight joint.

Please Note
Do not use in continuously submerged applications. Tape must be under minimum 30% compression to achieve an effective seal. Users are advised to conduct their own
tests in order to determine the suitability of the product for the particular application. Contact of the tape with solvents or corrosive chemicals should be avoided.
