Very high bond tape

Please order by the metre.


The ideal tape for sticking our uPVC angle to window frames (painted or unpainted surfaces). 1mm thick. Widths are approximate. Although this is a very flaxible adhesive it makes a rock solid bond. Apply with great care in case it grips the wrong spot! All surfaces must be clean, dry and free from grease and silicone*. It is almost impossible to pull off immediately after it has been applied, except by cutting, ripping it away or pulling the paint off with it.


*Like nearly all adhesives this will not stick to silicone products, so any smears must be physically eliminated.
