Permabond 4C30 is a medium-viscosity, medical-device-grade cyanoacrylate for medium gaps — fast-setting, ideal for automated dispensing with robots and static mixers.

Permabond cyanoacrylate instant adhesives in medical device grade — biocompatible (ISO 10993), solvent-free, cross-link in seconds through surface moisture between the components. 4C30 is tailored to specific applications — the most important properties and areas of use are listed below.

Medium viscosity for medium gaps

Permabond 4C30 is a medium-viscosity variant in medical device grade — reliably fills medium gaps, hardens quickly and is ideal for automated dosing systems.

processing

1
clean substrate
Degrease bonding surfaces with Permabond Cleaner A or acetone/isopropanol — a clean surface is critical for medical device bonding.
2
Polyolefin primer (if required)
For PP, PE, PTFE or silicone: Brush on Permabond POP Primer, let it dry briefly — otherwise no CA adhesion is possible.
3
CSA activator (if required)
For porous or difficult substrates: Spray on CSA aerosol, allow to evaporate — accelerates CA curing.
4
Apply cyanoacrylate sparingly
Apply a drop or thin bead to an adhesive surface — not on both sides, otherwise the reaction will be too rapid.
5
Joining + Pressing
Join components immediately and correctly aligned, press with defined pressure — adhesive spreads into a thin film.
6
Curing
Handling strength after seconds to minutes depending on the substrate. Final strength after 24 hours. Medical device compliance after full crosslinking.

Frequently asked questions about 4C30

Practical application and design questions — answered by SILITECH.

Permabond 4C30: Medium-viscosity, medical-device-grade cyanoacrylate for medium gaps — fast-setting, ideal for automated dispensing with robots and static mixers. Main applications: Automated medical device assembly, medium gap filling, static mixer processing.

Medical-device-grade cyanoacrylates meet enhanced purity standards for medical applications—typically ISO 10993 tests (biocompatibility, cytotoxicity). They have the same instant curing chemistry as standard CAs (crosslinking by surface moisture), but with controlled purity of ingredients for use in medical devices with patient contact or in pharmaceutical products.

Store in the unopened original container in a dry, cool place — Permabond adhesives typically between +5 and +25 °C, see TDS for exact values. Consult the Safety Data Sheet (SDS) before use. Observe the expiry date on the packaging. Store cyanoacrylates in a cool place (ideally refrigerated) for maximum shelf life.

The comparison table above lists related Permabond products with different properties—viscosity, mixing ratio, special certification. If you are unsure which product is best, we would be happy to advise you—contact SILITECH with your specific application (substrate pairing, load, curing conditions).
