Product Description of Permabond® Initiator 44
Permabond® Initiator 44 is used in conjunction with Permabond TA (structural acrylic) adhesives as a no-mix resin and initiator system. Its solvent free formulation allows a long open time if required. Alternatively, parts can be bonded immediately after application (no need to wait for evaporation)
Features and benefits of Permabond® Initiator 44
- Brush on liquid
- Quick & easy to use Use with Permabond® TA4590 and TA4591
- Structural Acrylic (TA) adhesives for rapid cure and fast strength development
Directions for Use
◼Surfaces should be clean, dry and grease-free prior to initiator application.
◼Permabond® Initiator 44 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
