There are different kinds of adhesives and one of these is the instant adhesive. Instant adhesive or the cyanoacrylate adhesive is one part solvent free that will cure immediately at room temperature. Instant adhesives offer strong bonding among materials.
The instant adhesives was first introduced and developed in the year 1949 by Alan E. Ardis from the Goodrich Company in the United States. This was later developed to become a marketable product by F.B. Joyner and Hawkins at the Eastman Company. The product was marketed to the public by Eastman Company in 1959. Since the 1960s there were a lot of companies from across the globe that enhanced and manufactured improved adhesive products. They refined the methods of synthesizing the main ingredient to the product which is the monomer. The instant adhesives have different unique characteristics that make it distinguishable from other types of adhesives. Because it has inherent special features, the instant adhesives are widely used in various applications both at home and in different industries.
Advantages and disadvantages
The instant adhesives that are commonly used for different applications today are usually either ethyl cyanoacrylates or methyl cyanoacrylates. Ninety percent of the products are usually ethys acyanoacrylates. The following are the advantages of using instant adhesives:
- instant bonding
- high bonding strength
- cured at room temperature
- it is one part catalyst free
- it encourages high electric insulation
- it can resist to chemical bonding
- you will only be required small volume when using the product
The following are the disadvantages of using the product:
- it has low heat resistance
- low resistance to impact
- it has low elasticity
- it is only applicable in applications with small clearance
- it is not applicable when bonding materials with large surface area
- it has an irritating odor and it causes blooming
- it can be irritating to the skin since it bonds well with it that is why you need to be extra careful when handling the product
- you need to be cautious when storing the product and ensure that it is out of reach from children
The instant adhesives are practically very easy to use and are widely used because it has instant bonding results. The substance is able to react immediately and bonds the structure or materials instantaneously at room temperature. Looking it at another angle, the instant adhesives are characterized to have low impact, water and heat resistance and it is because of these characteristics that they become less suitable when used as bonding agents when compared to acrylic adhesives or epoxies for structural components. However, it is believed that this downside for the instant adhesives can be overcome by adding new chemical groups in the molecular composition of the product. You can also combine the instant adhesives with elastomers in order to achieve a more improved product in the future. Instant adhesives are a handy product in that they have a wider application when it comes to the field of electronics and electrics.
