Permabond Initiator 41

Permabond Initiator 41 is a solvent-free initiator, designed for use with structural acrylic adhesives. The initiator is versatile in its application, where it can be sprayed, brushed or wiped onto the part to create a thin even coating. The formulation allows a long open time or alternatively parts can be bonded immediately after application.


  • Suitable for use with Permabond structural acrylic (TA) adhesives


  • Brush on liquid
  • Quick application
  • Easy to use

Surface Preparation

  • Surfaces should be clean, dry and grease-free prior to initiator application.
  • Permabond® Initiator 41 should be applied either by wiping (using a clean cloth), spraying or brushing onto part. For best results it should be a thin even coating.
  • Permabond® TA structural acrylic should be applied to the corresponding part.
  • When the two parts marry, the adhesive is reacted and will cure. Parts should be clamped firmly and not disturbed for the duration of the handling time (as per table on the left).
  • Excess initiator can be cleaned off using a suitable alcohol (such as isopropanol, acetone or MEK).
  • For maximum bond strength, allow adhesive to cure for 24 hours at 23°C.
  • Permabond® Initiator 41 is formulated to minimise attack and maximise performance on certain plastics. However, it is recommended that the product is tested for compatibility prior to use in production.
