## Product description

Double-sided tape for splicing applications. One side of the substrate is coated with a green polysiloxane adhesive with high initial tack. On the other side there is an acrylic adhesive which still provides good anchorage to low energy surfaces and which will cure further after exposure to heat.

Structure:

```text
   (A)    liner:            PET, double-sided siliconized
   (B)    adhesive layer:   polysiloxane, green
   (C)    substrate:        PET 50 µm
   (D)    adhesive layer:   acrylic adhesive
```
