Frequently asked questions about Initiator 46
Practical application and design questions — answered by SILITECH.
Permabond Initiator 46: No-Mix activator for Permabond TA4246 Aerospace structural adhesive — Amber, 70 mPa·s, high flash point (>140 °C). Main applications: Aerospace structural bonding, high-demand bonding, Aviation OEM.
Permabond TA structural adhesives use a no-mix system: the initiator is brushed onto one bonding surface, and the TA adhesive onto the other — when joined, they react between the components. No pre-mixing, no pot life limitation of the mixed mass. On-part life 30 minutes — components can be assembled with the TA adhesive after a delay following initiator application. Ideal for high-throughput structural bonding.
Store in the unopened original container in a dry, cool place — Permabond adhesives typically between +5 and +25 °C, exact values see TDS. Consult the Safety Data Sheet (SDS) before use. Observe the expiry date on the packaging. Store cyanoacrylates cool (ideally refrigerated) for maximum shelf life.
