Super glue

Jump to navigation Jump to search


The name Super Glue was first used by Loctite in 1973 for a cyanoacrylate adhesive. However, before the name was trademarked it was also used by other companies for the fast-setting cyanoacrylate adhesives. In general, these are colorless, transparent adhesives. Cyanoacrylate glues set rapidly (5 seconds to 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.

Working Properties

Avoid contact with eyes, skin and clothing. Avoid breathing vapors or mists of this product. Wash thoroughly after handling. Avoid contact with fabric or paper goods. Contact with these materials may cause rapid polymerization which can generate smoke and strong irritating vapors and cause thermal burns.

Keep in a cool, well ventilated area away from heat, sparks and open flame. Keep container tightly closed until ready for use as humidity and high temperature may decrease shelf life.

Super Glue does not bond to Polyethylene (PE), polypropylene (PP), polytetrafluoroethylene (PTFE), silicone or foam rubber, polystyrene foams, glass, or pure bone china. Do not use on glazed surfaces. Not for exterior applications. [1]

Surfaces need to be free from dirt, grease, or oil so that a strong bond can form. Apply above 50°F and leave undisturbed for 5-10 minutes, but for best results leave overnight to allow for full bond strength.

When cured, Super Glue become a clear and colorless brittle solid. Scrape away excess cured adhesive with sharp-edged tool.
