Super glue: properties, usage tips, what can you stick with?


Super glue is a very practical product for individuals and for many professionals. Indeed, with its almost immediate setting, it allows you to glue multiple materials with an aesthetic and discreet effect. Its grip has the great advantage of being durable, resistant and fast. Let’s take stock of the properties of this product, what it allows to stick and on the advice to follow to use it properly.

Super glue: what are its properties?

Super glue is a product invented in 1942 by Doctor Harry Coover and discovered accidentally. Indeed, it is while wishing to create transparent plastics for the use of high precision sights that this researcher discovered cyanoacrylate, a chemical compound with considerable adhesion. It was only later that the scientist realized the interest of his fortuitous discovery and its commercialization was launched by Eastman Kodak in 1958. In 1960, the household super glue Loctite was born.

The super glue that we know today is a one-component cyanoacrylate glue made from cyanoacrylic acid very powerful and fast-acting which allows to bond many materials with high efficiency. Some derivative models are able to withstand large variations in temperature and humidity, which makes them formidable on many exterior materials. Some variants are also specialized for bonding materials with particular specificities.

Super glue glues quickly and extremely well two pieces of the same material or two pieces of certain different materials. It is resistant to water and many stresses, especially after a 24 hour installation. Its setting is immediate and definitive for a solid, resistant and lasting repair. Its particularity is that it polymerizes thanks to the humidity of the air. The speed of the setting is linked to the latter.

A super glue with various viscosities

In addition, a distinction is made between super glue gel and liquid. Liquid formulas are more suitable for bonding cracks, because they penetrate more easily into small holes and they dry faster; they are ideal for smooth materials. On the other hand, gel models are preferred for precision work, as they flow less, an advantage for porous materials. In reality, there are four categories of viscosity for super glue, from fluid form to gel through medium viscosity and high viscosity.

An advantageous and practical product

Super glue has the advantage of allowing immediate or almost immediate setting. Easy to dose, it is perfectly colorless and remains discreet. It has very little odor and is available in several viscosities to meet a wide range of needs.

How to use super glue?

Super glue is capable of bonding many materials, such as metal, plastic, glass, rubber, wood, leather, porcelain, ceramics, paper and many more.

To successfully glue with super glue, you just need to follow five simple steps:

  • Step 1: prepare your surface : for better grip and a smudge-free result, be sure to clean the surfaces to be glued, and above all to remove dust and degrease them.
  • Step n ° 2 : correctly position the pieces : before gluing two pieces, make sure to carefully place them so that they are perfectly aligned. You won’t get a second chance.
  • Step n ° 3 : apply super glue : on only one of the two sides to be glued, apply super glue in sufficient quantity and harmoniously distributed. Avoid putting too much super glue on, as this delays curing and causes unsightly smudging.
  • Step n ° 4 : glue the surfaces: it’s time to glue the two surfaces together. Strongly press the two elements together for at least 10 seconds. Don’t wait to wipe off any super glue smears that have spilled over with a damp cloth. Then carefully close the tube.
  • Step n ° 5 : wait: if the setting is immediate or almost immediate, wait 24 to 48 hours to handle a delicate object, because the complete setting requires this time. You will avoid having to start pasting again.

If you’ve stuck your fingers together or on an object, soak them in lukewarm soapy water and gently rub them apart. The glue gradually crumbles until you are released.
