What are ingredients of 502 glue?

The scientific name of 502 glue is α-Cyanoacrylate adhesive .
1.Binders. The main binders of 502 glue are α-Cyanoacrylate adhesive and acetaldehyde with high bonding strength.
2.Thickener. The viscosity of monomers is low and easy to flow. It is inapplicable to bond porous material and fill gaps without thickener. The usual thickeners are PMMA, polyacrylate, cyanoacrylate and a derivative of cellulose.
3.Plasticizer. In order to improve the brittleness of adhesive and impact strength, it is common to add plasticizer, such as dibutyl phthalate ( DBP) and dioctyl phthalate( DOP).
4. Stabilizer. Monomers occur polymerization. So it is necessary to add some stabilizer such as hydroquinone in case of polymerization of anions and free radicals.
