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-performance bonding, aviation OEM.
Permabond TA structural adhesives utilize a no-mix system: initiator is brushed onto one bonding surface, TA adhesive onto the other—they react between the components during joining. No pre-mixing is required, and there is no pot life limit on the mixed compound. On-part life is 30 minutes—components can be joined 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, 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.
