Technical Information Property Foam Density Tensile Strength Water Absorption Resistance to Chemicals Acids Mineral Oil Alcohol Alkalis Petrol Soap & Detergents Ozonr and Salt Water Spray Good Good Good Good Good Good Good TN545 Water, Air & Dust Seal Usage / Purpose TN545 is a single sided high density PVC foam tape which when compressed by 30% can be used to foam a water and air/dust seal. Suitable in applications requiring heavy compression. Compression Required to Achieve a Positive Waterseal Compression Deflection After 1 Minute Peel Adhesion 180° 10 Minimum Dwell Application Temperature Service Temperature Store in shaded dry conditions not exceeding 23°C and 50% RH Shelf Life 24 months when stored as recommended in original unopened packaging Preparation • 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. Insulation performance against shock, vibration and movement • When under compression (30%), provides an effective weather seal against wind and rain • Provides a barrier to thermal bridging, galvanic corrosion and acoustic transmission • Pale blue release paper on the nonadhesive face to prevent stretching when applying an

illbruck Water, Air & Dust Seal Application • 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. • The assembly must provide sufficient force to compress the tape by 30% of original thickness if a weatherseal performance...
