Cyanoacrylate glue consists of a single compound: a generally ethyl cyanoacrylate base with different levels of fluidity, solvent-free and very fast curing at room temperature (under the influence of air humidity). This glue also has a very strong adhesion which is why it is called “superglue”.
The single component cyanoacrylate glue has several viscosity levels depending on the nature of the substrates: for smooth materials (such as metals), a liquid glue should be preferred, whereas for porous materials (such as ceramics), we will choose a gel glue.
