The "Invisible" Bonding Solution for Graphic Overlays.
Charmetack’s **Adhesive Transfer Tape** consists of a pure layer of high-performance acrylic adhesive coated on a release liner, with **no carrier backing**.
Engineered as a cost-effective alternative to **3M 467MP / 468MP**, this tape offers exceptional transparency and conformability. It flows into the micro-textures of surfaces, creating a permanent bond for thin flexible materials like membrane switches, nameplates, and foam gaskets.
Why Choose Transfer Tape?
- 3M Equivalent Performance: Delivers the same high shear strength and temperature resistance as industry-standard brands but at a factory-direct price.
- Extreme Conformability: With no stiff carrier, the adhesive "wets out" perfectly on textured plastics and rough metal surfaces.
- Ultra-Thin Profile (0.05mm - 0.13mm): Adds virtually no thickness to the final assembly, crucial for slim electronic devices.
- Die-Cut Friendly: Supplied with high-quality Glassine or Kraft liners for precise rotary die-cutting.
Technical Specifications
Comparable to standard 200MP adhesive systems.

- Foam Lamination: Pre-applying adhesive to gasket foams.
FAQ: Transfer Tape
Q: Is it hard to handle since it has no carrier?
It requires careful handling. We recommend using an ATG gun (Adhesive Transfer Gun) or automated laminating machines for application. Once the liner is removed, only the sticky glue remains.
Q: What is the difference between 0.05mm and 0.13mm?
Use 0.05mm (2 mil) for smooth, flat surfaces like glass or polished metal. Use 0.13mm (5 mil) for textured or rough surfaces, as the thicker adhesive
