Super Glue, or colle Cyanoacrylate, is a strong adhesive which works well on many materials, but there are some materials that it does not glue not effectively or for which it does not work at all.
Here are some examples:
-
Surfaces too smooth and non-porous :
- Polyethylene (PE) and Polypropylene (PP) : These are plastics often used in everyday objects such as bottles and packaging. Cyanoacrylate Super Glue does not adhere well to these plastics without a special primer.
-
Silicone and Teflon :
- These materials are very resistant and have non-stick properties, therefore the Super Glue Cyanoacrylate can't adhere to it well.
-
Soft rubber :
- Soft rubber, such as that used in gaskets or gloves, does not allow good adhesion of the Super Glue Cyanoacrylate, because it is too flexible and elastic.
-
Damp or wet surfaces :
- The Super Glue Cyanoacrylate needs a dry surface to adhere well. On wet surfaces, the glue will not harden properly.
-
Textiles :
- Although the Super Glue Cyanoacrylate may work temporarily on some fabrics, it is generally not effective for soft, porous textiles because it hardens and becomes brittle.
-
Materials too porous :
- Very porous materials, such as raw wood or certain types of stone, can absorb the moisture too quickly. cyanoacrylate glue before it can harden properly.
