Permabond Initiator 41 is a no-mix activator (amber, <50 mPa·s) for Permabond TA structural adhesives — long open time possible, solvent-free, for brushing or spraying.

Permabond initiators for the TA structural adhesive range — no-mix activators for brushing or spraying on before the acrylate adhesive for immediate or delayed curing. Initiator 41 is tailored to specific applications — its key properties and areas of use are listed below.

No-mix activator for TA adhesives

Permabond Initiator 41 is used in conjunction with Permabond TA (Structural Acrylic) adhesives as a no-mix resin and activator system. Its solvent-free formulation allows for a long open time—alternatively, components can be joined immediately without waiting for evaporation.

Frequently asked questions about Initiator 41

Practical application and design questions — answered by SILITECH.

Permabond Initiator 41: No-mix activator (amber, <50 mPa·s) for Permabond TA structural adhesives — long open time possible, solvent-free, brush or spray application. Main applications: Permabond TA structural bonding, long working time, instant bonding.

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.

The comparison table above lists related Permabond products with different properties—viscosity, mixing ratio, special certification.
