Cyanoacrylate Adhesive or Superglue or Powerglue

This adhesive is named by superglue because that use and function of this adhesive in many purpose and some is amazing, look on the description bellow that superglue have many purpose even in surgery and in criminal detection.

Cyanoacrylate adhesive is adhesive that work very fast in small quantity. Very fast to dry and very stick to tie of both materials. Cyanoacrylate adhesive commonly based of methyl-2-cyanoacrylate and ethyl-2-cyanoacrylate. This adhesive usually sold with trading name of Super Glue and Power Glue.

Cyanoacrylate adhesive can use in many kind of material even on the material that contain little of water or wet material. Because cyanocrylate can work in wet material so they often use in surgery, but the stick function of this glue just for temporary because after several day the glue will shear and loose, the glue very useful on first stick helping, afterward the tissue will grow and stick as normal tissue.

Cyanoacrylate adhesive often use in electronic, modeling kit or designer and in aircraft flying model. Cyanoacrylate adhesive is not purpose for porous material, more function on smooth material like plastic or metal, but don’t have a good bonding on smooth glass. To have a good bonding on gluing material we can use fiber glass to reinforce the bonding.

If work with porous material we can mix cyanoacrylate adhesive with baking soda (sodium bicarbonate). Baking soda will use as filler on glue process working baking soda will fill the porous first then power glue will dip into the baking soda and make a strong stick. This method also use in repair of small nicks in the leading edge of composite propeller blades on light aircraft. Intension on this working that the reaction of baking soda and cyanoacrylate is exothermic reaction (produce heat) and will exert noxious vapors.

Cyanoacrylate adhesive also use in criminal identification, in a forensic method as latent fingerprint on non porous material such as glass and plastic. The work of this glue by warmed of Cyanoacrylate to produce fumes which react with the invisible fingerprint residues and atmospheric moisture to form a white polymer (polycyanoacrylate) on the fingerprint ridges, this ridges then can be recorded.

In Indonesia normally this product is imported from other country like Korea and China, but Indonesia more prefer from China because cheapest one eventhough the quality is not good. For better product like Superglue is imported from many country, Korea, Japan, United Stated and Germany.
