For the usual activated products, this content is of the order of 0.6 to 0.3 mol water per mol alumina and their specific surface, measured' by nitrogen adsorption at-l95' according to the BET. method, attains 200 to 250 sq. meters per gram, which corresponds to an excellent activity.
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.
White school glue and yellow wood glue are water based. You apply and the water evaporates. Super glue is just the opposite. It actually cures with water. It draws water from the air or the surface of the items being glued. Curing is caused by water vapor on the surfaces or in the air. (Most all surfaces have some water from the surrounding air, therefore humidity can affect bonding.) Super glue contains its own hardener.
