Product Description

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.

Processing

1
Clean substrate
Degrease bonding surfaces with Permabond Cleaner A — a clean surface is critical for the No-Mix system.
2
Brush or spray on the initiator
Apply thinly to one bonding surface — on-part life 30 min.
3
Apply TA adhesive
Apply Permabond TA structural adhesive to the other bonding surface.
4
Joining components
Bring components together — immediate reaction between initiator and TA resin.
5
Curing
Fast curing — handling strength within minutes. Final strength according to TA type.

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 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.
