Acrylic Adhesives. Acrylic adhesives can either be water-based (this is also referred to as emulsion or dispersion) or solvent-based. Water-based are slower drying compared to solvent-based systems but generally solvent-based acrylic systems have better resistance to other solvents, chemicals and water.
Strong adhesives include epoxies and Super Glues. In this article, we are discussing about the two strongest adhesives, super glue and epoxy. Super Glue. Super Glue is a form of compound cyanoacrylate. Methyl 2-cyanoacrylate and Ethyl 2-cyanoacrylate are two of the most popular types of super glues.
