[Borden] A registered trademark for a cyanoacrylate adhesive. Krazy® Glue contains 99.95% ethyl cyanoacrylate and 0.05% acrylic. Cyanoacrylates are quickly polymerized by exposure to moisture and ultraviolet light. When cured, it forms 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

Krazy glue; crazy glue (sp); cyanoacrylate



Other Properties

Uncured glue soluble in acetone and methanol. Cured glue is slightly soluble in DMF or nitromethane. Soaking in acetone may decrease adhesion and cause the join to separate.

Hazards and Safety
