Description
A thermoplastic polymer commonly used as a fast-setting, strong adhesive. The first cyanoacrylate adhesive was made in 1941, but not marketed till 1958 as Eastman 910® [Eastman Kodak]. Cyanoacrylate adhesives are based on ethyl-2-cyanoacrylate polymers. Most commercial formulations also contain stabilizers, thickeners and catalysts. The glues set rapidly (5 seconds - 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. 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.

Applications
- Adhesive
Personal Risks
May cause irritation to skin and eyes. Will adhere objects on contact, including skin. Flash points range from 75-80°C.
Environmental Risks
Formaldehyde degradation product (more so in ethyl type).[1]
Collection Risks
- Hydrolysis degradation can occur in alkaline conditions (glass surfaces).[1], [2]
- Cyanoacrylates undergo ultraviolet degradation.[1], [2]
Physical and Chemical Properties
- Uncured glue soluble in acetone, methanol, toluene, MEK.
- Cured glue is slightly soluble in DMF or nitromethane.
- Soaking in acetone may decrease adhesion and cause the join to separate.
- CAS = 7085-85-0
- Density = 1.05-1.10
Working Properties
Cures quickly
Forms/Sizes
Often sold in small container with application device
