Why does Kapton tape leave silicone adhesive residue despite its 260°C rating?

Adhesive transfer occurs when heat exposure causes thermal shear degradation of un-crosslinked silicone, or when high peak wave soldering temperatures break down the chemical bond between the polyimide backing and adhesive coating layer.

How does storage time affect Kapton tape liner release force and tack?

Over extended storage (>6-12 months), release agents from the PET liner can migrate to the silicone pressure-sensitive adhesive. This reduces surface tack while increasing release force, causing liner lockup and difficulty in high-speed automated peeling.
