Quick glue or super glue – An explanation of how cyanoacrylate glue works and how best to use this glue

Quick glue or super glue is an effective for quick repairs. The glue often hardens in a few seconds and is able to glue several different materials and surfaces. Which super glue is best is difficult to answer directly. Different super glues, or cyanoacrylate glues, have differences in viscosity, which can be beneficial for different materials.

Quick glue adheres excellently to most different types of materials. Materials that stick well with instant glue are usually plastic, rubber and can also be used for metal. However, instant glue or cyanoacrylate glue for glass is not recommended. Usually it is best if the glue joint is thin. Adhesive joints that are too thick run the risk of breaking faster and the joint will not be nearly as strong.

Quick glue is mainly used for gluing smaller details in plastic or rubber. Other examples of areas of use are in electronics, 3d printing, 3d models or hobby projects.

How does instant glue work?

Instant glue or cyanoacrylate glue is a hardening glue, a thermosetting plastic. It hardens through a chemical reaction with water. But not a lot of water is required. In normal room humidity, there are water molecules present on various surfaces. This small amount of “water” or moisture is enough for the instant glue to set and harden. This also means that the lower the humidity in the air, the longer it takes for the glue to harden.

Porous and acidic surfaces such as paper, leather, wood, chromed steel are difficult to attach well with cyanoacrylate glue.

Also remember to check that your instant glue has not passed the expiry date. An opened bottle ages faster as moisture enters the tube. That’s why we also have small practical tubes for small jobs.
