Description
[Elmer's] A registered trademark for a cyanoacrylate adhesive. Krazy Glue contains 99.95% ethyl cyanoacrylate and 0.05% acrylic. Krazy Glue is a clear, colorless liquid before curing. 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
Applications
- Adhesive
Personal Risks
- Causes eye irritation and may cause allergic skin reaction and respiratory irritation.
- Suspected of damaging fertility or the unborn child.
- Will adhere objects on contact, including skin.
- Elmer's: SDS
Collection Risks
- May polymerize when heated, unstable at elevated temperatures.
- Containers may rupture or explode when exposed to heat.
- Avoid contact with water or moisture.
- Avoid contact with light.
- Oxides of carbon are hazardous decomposition products of Krazy Glue.
Physical and Chemical 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. [1]
Working Properties
Incompatible with alcohols, amines, and bases. Krazy Glue does not work well with paper, foam, polyethylene, Teflon, or other fluorocarbons. [2]
Water vapor is the catalyst that activates the Krazy Glue bond, so keeping the cap on the tube when not in use is essential. [3] A tight bond is formed within about 10 to 30 seconds and Krazy Glue does not expand as it cures, so clamps are not necessary. Surfaces need to be free from dirt, grease, or oil so that a strong bond can form.
Forms and Sizes
| All Purpose: | Works on wood, rubber, glass, metal, plastic, and ceramic |
|---|---|
| Gel: | “No-run” formula; useful for filling gaps on porous surfaces or gluing together mismatched surfaces. |
| Maximum Bond: | Extra strong, durable shock-resistant bond |
| Craft: | Made for use on materials such as ceramic, porcelain, and wood |
| Wood: | Formulated for porous wood including maple, pine, birch, red oak |
Krazy Glue also has a variety of tips, brushes, and applicators.
Sold in small tubes, sizes vary from 0.07-0.52 oz. depending on formula and applicator type.
