Octyl cyanoacrylate was developed to address toxicity concerns and to reduce skin irritation and allergic response. Cyanoacrylate adhesives are sometimes known generically as instant glues, power glues or superglues (although Super Glue is a trade name). The abbreviation CA is commonly used for industrial grades.
It is ethyl 2-cyanoacrylate (CA). It is typically composed of about 90% ethyl 2-cyanoacrylate and 10% other compounds with traces of an organic acid. Thinner glues are most likely primarily CA. Super glue bonds all kinds of materials but does not work well on the super smooth surfaces, like glass.
