A bond accelerator: for all cyanoacrylate adhesives, including Hot Stuff. Can be used before or after adhesive is applied. Especially useful when more than a drop or 2 of hot stuff is needed, as cyanoacrylate does not bond quickly in larger quantities. One spritz from the spray pump bottle is all that is needed. On close fitting parts, apply adhesive, then spray edge and NCF will cause a chain reaction bond to occur. Use very small quantities to avoid causing the adhesive to turn white, and for economy.
