Permabond QFS16 Cyanoacrylate Activator

The PERMABOND QFS 16 accelerates the cure of cyanoacrylate adhesives to provide a shorter set time. It can be used in a variety of applications but is especially useful when bonding porous or poorly mated parts. PERMABOND QFS 16 cures the adhesive before it soaks into a porous surface or runs out from between parts with sizable gaps. It can be used to accelerate cure on sensitive plastic surfaces such as polycarbonate without causing stress cracking. No discoloration of the part surface is observed when using PERMABOND QFS 16. The activator can be sprayed on the surface of the cyanoacrylate to accelerate curing in wire tacking or similar bonding applications. PERMABOND QFS 16 contains a specially chosen initiator in a non-halogenated solvent that is not ozone depleting. This solvent evaporates quickly to leave a thin film of the initiator on the surface to be bonded. Features & Benefits: Contains no ozone depleting agent Rapid setting on closely mated parts Faster cure through gaps Enables cyanoacrylates to bond to porous surfaces Will not stress crack plastic surfaces No discoloration of part surfaces Reduces frosting or fogging of the adhesive Allows cyanoacrylates to cure on strongly passivated metals, aged PVC or acidic surfaces such as wood Typical Applications: Porous Parts Poorly Mated Parts Wire Tacking Reduction of Stress Cracking on Plastic Parts Information provided by Permabond.
