CSA-NFTraditional cyanoacrylate accelerators contain flammable solvents; Permabond® CSA-NF is non-flammable and eliminates shipping and safety concerns related to flammable solvents.

Cyanoacrylate adhesives are single component adhesives. They cure by reacting to small traces of moisture on the surface of the substrates.  Accelerators speed the cure on very dry or acidic surfaces and on porous surfaces to cause cure prior to the adhesive wicking into the porous substrate.  Additionally, they quicken surface cure to a clear non-tacky finish with no white residue. 

 Permabond cyanoacrylate accelerator CSA-NF is appropriate for all Permabond cyanoacrylates. The line includes products that vary in; adhesion to different substrates, viscosity, color, temperature resistance, gap filling capability, cure speed, and compatibility, as well as Permabond’s high performance cyanoacrylates which include rapid cure, high temperature resistance, surface insensitive, non-blooming, low odor and impact resistance. 

Cyanoacrylate Accelerator Directions for Use

◼Surfaces should be clean, dry, and grease-free prior to primer application.
◼Apply Permabond CSA-NF by wiping (using a clean cloth or brush), spraying, or dipping one component.
◼Allow CSA-NF to dry before assembling the joint.
◼Apply Permabond cyanoacrylate adhesive to the untreated surface. Mate the two parts quickly.
◼Do not put the adhesive on the treated surface. The adhesive could cure before the parts can be properly mated. Only if the gap is extremely large (>0.5mm) can the activator be applied to both surfaces.
◼For maximum bond strength, allow the adhesive to cure for 24 hours at 23°C.
◼Permabond CSA-NF is formulated to minimize attack and maximize performance on certain plastics. However, test for compatibility prior to use in production.
For post-applying (e.g. for curing excess adhesive fillets or for wire tacking):
◼Lightly spray or drip activator onto uncured adhesive (do not react large quantities).
Do not mix Permabond CSA-NF directly with cyanoacrylate adhesives.
