Application and use

The PSA 63Vst is characterized by an extraordinary high tack. Even on critical surfaces tack-level is very high. 63Vst is therefore ideal for cool, moist and even slightly greasy surfaces. Despite the excellent low temperature properties, it indicates very good mandrel-hold and is therefore suitable for curved surfaces and irregular 3D packaging.
Once labelled 63Vst is highly waterproof.


Excellent die-cutting characteristics on all customary machines.
