Heat activated sealing tape for 2 layer fabrics. Width 20mm.

Matte and transparent, high industrial quality from eu supplier. PU based so it sticks well to PU and TPU coated fabric. It also sticks to fabric with good texture.

• No crack
• No yellowing
• Matt Transparence
• Soft touch
• Almost invisible once applied

Available in two thickneses:

  • Thin (for the most lightweight applications); Heat setting: 140-180°C . Great for use with 10D, 20D and 30D fabrics.
  • Thick (slightly thicker, easier to work with for beginners and on curved seams, its thickness allows for the depth penetration in fabric fibers, blocking the seam holes left by the
    needle and the thread, restoring good impermeability to water, liquids and air. Heat setting: 140-180°C

Width: 20mm

As with most seam sealing tapes on the market it’s important to orientate the tape correctly. They have glue on one side and skin on the top. This means one side sticks better to the fabric you want to seam seal and the other is processed in a way that sticks less to the iron /tool. For best results try ironing on the smoother side and apply pressure. On the thin tape it is hard to figure which one is correct just by touching so just try which side sticks notably less to your iron.

If you use domestic iron, try with the lowest setting first.

Try iron settings and fabric compatibility on some scrap fabric before applying it to your project!

    “Thin” variant is very thin compared to other seal tapes I used previously. Great for ultra light stuff. Sticks really well to PU coated nylon.
