BLOW Kapton tape 6289# is a self-adhesive polyimide film tape, 20 mm wide and 33 m long, designed for applications requiring stable performance at elevated temperatures. The tape provides electrical insulation, chemical stability and dimensional stability, making it suitable for electronics assembly, PCB masking during wave or reflow soldering, and high-temperature repair tasks. Its thin profile and consistent adhesive backing enable precise application on small components and assemblies.
Advantages
The tape resists high temperatures while maintaining adhesion and dielectric properties, ensuring reliable masking and insulation in soldering or thermal processing environments. Its polyimide carrier offers excellent chemical inertness and low outgassing, which helps protect sensitive electronic components. The product’s narrow width and flexible film construction allow accurate placement on traces, leads and connectors without leaving significant residue after removal when used within recommended temperature ranges.
Suitable for
- PCB masking during reflow and wave soldering
- Insulating and wrapping wires and cable bundles
- High-temperature repairs and component protection
- Precision masking for conformal coating and selective coating processes
- Industrial and hobby electronics assembly and prototyping

How to use
Ensure the surface is clean, dry and free of oils or dust before application. Cut or tear a suitable length of the tape and apply it smoothly to the target area, pressing along the tape to ensure full contact and eliminate air pockets. For masking during soldering, cover areas that require protection and ensure edges are sealed to prevent solder wicking. After thermal processing, remove the tape carefully once the assembly has cooled to avoid stretching or leaving adhesive residue. Store the roll in a cool, dry place away from direct sunlight to maintain adhesive performance.
Usage recommendations
Use the tape within its recommended temperature range and avoid prolonged exposure well above soldering temperatures to minimize adhesive transfer. For long-term insulation on high-voltage or mechanically stressed connections, verify compatibility with the specific operating environment. When precise masking is required, consider using a narrower width or multiple strips to achieve clean edges.
