CA adhesives

Cyanoacrylates are mainly used as adhesives. They require some care and knowledge for effective use: they do not bond some materials: their shelf life at room temperature is about 12 months unopened and one month once opened. The shelf life can be approved when stored in a refrigerator. The cyanoacrylate does not fill spaces, unlike epoxies, and a very thin layer bonds more effectively than a thicker one that does not cure properly, they bond many substances like natural fibres: cotton, wool, leather but also rubber and so on.
