- Fast fixture
- Single component and easy to use
- Transparent adhesive joint
- Good mechanical resistance
Cyanoacrylate adhesive is a single component adhesive with fast fixture, especially used for bonding plastics, glass, metal and rubber. It is very suitable for bonding on small surfaces. The basic principle of cyano adhesives is to polymerize in the presence of moisture in the air. Depending on the state of the surface to bond, different adhesive viscosities enable you to have an effective assembly.
4 main categories of cyanoacrylate adhesive viscosity can be distinguished :
- Fluid (5 cPs) fluidity equivalent to water : adhesive can be applied when parts are already in place
- Average (100 cPs) fluidity equivalent to olive oil : for conventional applications
- High (1500 cPs) fluidity equivalent to liquid honey : for irregular or porous surfaces
- Gel (Thixotropic, doesn’t drip) : for applications where large gaps need to be filled
Cyano acrylate adhesive is widely used by manufacturers and known by the general public (brand superglue).
Here are the main advantages :
- Fast fixture
- Single component adhesive
- High mechanical performance in shearing
- Easily applied
- Translucent colour
- Large choice of substrates and strong covering power
Depending on your final assembly, you may need to use complementary products from the range :
- Cleaner (clean oil and grease residue before bonding)
- Primer (to improve performance on some surfaces)
- Activator (accelerate polymerisation)
- Stain remover (clean cyanoacrylate residue or separate bonded fingers)
Some tips for choosing your cyanoacrylate adhesive ?
- For assembly of clear plastics, use a specific adhesive, without odour and that doesn’t bleach the plastic.
- For delicate assemblies, a very fluid adhesive will enable you to apply the adhesive without moving the joints.
- For repairing rubber joints, use cyanoacrylate rubber-filled adhesive that will give more flexibility to your assembly.
Some example of applications of cyanoacrylate adhesive ?
