Cyanoacrylates or instant adhesives are available in the market for a wide range of applications, but the most common one is making repairs. If applied on a damaged area, it induces properties that make it possible for the two parts to cure. In cases where the damage is deep, several layers of adhesive accelerator and the adhesive may be used to achieve a complete repair. Most of the times, the repair is cost effective and fast, considering the fact that the part regains its original strength
Why do we need an accelerator?
The adhesive accelerator is formulated from an active species dispersed in solvents like acetone and isopropyl alcohol. These active species form the base that has the capacity to begin a cure on the cyanoacrylate or instant adhesive. The adhesive accelerator is normally applied on the substrates that are to be bonded before applying the adhesive, so as to minimize the cure time. It is normally applied on one surface while the instant Adhesive is applied on the mating surface to keep the adhesive from curing on the accelerator before the two surfaces are actually mated. It is also possible to have the accelerator sprayed over the instant adhesive in unconfined drops. This is a widely used technique when tacking wires on printed circuit boards
