Permabond® 4C40 – High-performance medical adhesive for large gaps and difficult materials
Permabond® 4C40 is a medium to high viscosity single-component adhesive that has been specially developed for applications with larger gaps and for substrates that are difficult to bond, such as polyacetals and passivated metals. Thanks to its fast curing and universal applicability, it is ideal for industrial series production as well as for applications in medical technology. The Biocompatibility according to ISO 10993-5 and USP Class VI makes it ideal for disposable medical products and devices.
product features

Processing instructions
- Clean the surfaces to be joined and roughen them slightly if necessary.
- Apply adhesive sparingly to one side
- Align and press parts together, do not move them.
- Fixing time: 5–10 seconds, full strength after 24 hours
- For difficult substrates, use Permabond CSA or POP.
- Store at 2–7 °C; bring to room temperature before use.
