Highly Heat-Resistant
SX7700
 |
Features
- This highly heat-resistant adhesive can be used at temperatures of up to 150°C, maintaining stable adhesive properties even in harsh temperature environments.
- Contains no low-molecular siloxanes, which can cause electrical contact failure.
- Adheres well to various materials, including engineering plastics such as PBT.
- Environmentally friendly, solvent-free adhesive that is safe to work with.
