Cyanoacrylate resin
Description
A thermoplastic polymer commonly used as a fast-setting, strong adhesive. The first cyanoacrylate adhesive was made in 1941, but not marketed till 1958 as Eastman 910 [Eastman Kodak]. Cyanoacrylate adhesives are based on ethyl-2-cyanoacrylate polymers. Most commercial formulations also contain stabilizers, thickeners and catalysts. The glues set rapidly (5 seconds - 3 minutes) upon exposure to ultraviolet radiation or moisture. When cured, they form an extremely strong bond that is fairly insoluble. Cyanoacrylate glues has been used for gluing glass, ceramics and other hard materials. They also have medical and dental applications to suture skin and weld crowns. Some cyanoacrylate glues may lose adhesive strength with time. Ultraviolet light and contact with alkaline materials (glass and some stones) will accelerate the degradation process.
Synonyms and Related Terms
CA; super glue; instant adhesive; Super Glue Gel [Loctite]; Krazy glue
[Borden]; Super Attack [Loctite]; Zap; Eastman 910 [Eastman Chemical]; ELFY
super glue; ethyl cyanoacrylate; Dermabond; Traumaseal; cianoacrilati (It.); cyanoacrylaat (Ned.); resina de cianoacrilato (Esp.)
Other Properties
Uncured glue soluble in acetone, methanol, toluene, MEK. Cured glue is slightly soluble in DMF or nitromethane. Soaking in acetone may decrease adhesion and cause the join to separate.
