Air Fast spray activator is an aerosol activator which will give an instant cure if used with cyanoacrylate glue. This activator can be used before or after applying cyanoacrylate glue to surface which is to be bonded. It is commonly used with high viscosity or gel cyanoacrylates as the drying time for both of them are slow. The accelerator is solvent based and when applied dries immediately leaving a very thin layer of activator on the surface.
