Isotape® – Electrical adhesive tapes Isotape® 4428PV3

Isotape® 4428PV3 consists of a Kapton® film with silicone adhesive.

Isotape® 4428PV3 is manufactured from Kapton® film together with high performance silicone adhesive. It provides excellent protection for gold contacts on PCBs during wave soldering and hot air leveling processes. It is also designed for coil insulation at high temperature. For uses in generators, capacitors, transformers and others.
