Uses of Cyanoacrylate Adhesives

Cyanoacrylate Adhesives or more popularly known as CA glue is an umbrella term for quick bonding glues that fixes a variety of materials within no time. These are fast adhesives that can be used for household, medical or even industrial purposes. Since these adhesives are transparent in color and has the quality of excellent stability, it becomes a necessity for rectifying design flaws or in places where the fault requires to be covered well. There are a number of reasons behind the popularity of Cyanoacrylate Adhesives:

  • Fast curing time in room temperature
  • Low shear quality that allows shedding off later easily
  • Extremely rigid

Thin layers of Cyanoacrylate Adhesives works wondrous than a relatively thicker layer which also takes more time to dry. Leather, natural fibers, cotton, wool and even human skin or tissues can be glued together using Instant glue. Due to the low shearing quality but high toughness, these can be used on many surfaces where the skin needs to be peeled off later, for instance – for tightening bolts and nuts.

Another interesting purpose of Cyanoacrylate Adhesive is in crime scenes for detecting finger prints on plastics or glass that are otherwise latent. Besides, low odor quality of these CA Adhesives makes others impossible to guess that glue was used at all. In fact, these can also be used for underwater bonding. If the adhesive is applied on to a surface and then the material is put under water, it immediately hardens and sticks materials. This becomes possible due to the high viscosity of the CA Glue. Due to the low shear quality, it can be easily removed from surfaces using sandpaper or by rubbing sugar. Thus, it also makes great temporary glue. For prototype electronics, model aircrafts or electronic aficionados, CA Adhesive can be very effective.

Another reason for the huge usage of these adhesives is its non flammable quality and single component efficiency. Unlike other glues that often require two different kinds of adhesives for the bonding, CA Adhesive does not need other supporting agents to be efficient. It can be easily used on surfaces over which gasoline or motor oil is poured. It has great resistance to non polar solvents and therefore retains the bonding quality very well. Furthermore, Instant glue does not need mixing, preparing or heating. It is a simple one step bonding solution.

Many wood works require a glossy finish for which Cyanoacrylate adhesives are extensively used. For specifically this purpose, linseed oil is often mixed with CA glue to slower the curing time. Cyanoacrylate is not itself a filling agent. However, it is sometimes mixed with sawdust to make it age like one. Hence, it can be used on wooden furniture, soundboards, and wooden instruments. In many medical adhesives, Cyanoacrylate is being increasingly used because of its quick bonding and shear quality. Instrument players such as guitarists often use it on fingertips to protect the skin while playing. Even in cosmetics, Instant glue is used to stick eyelashes or fingernails.
