What are instant adhesives?
Instant adhesives are one-part solvent-free adhesives that were first developed in 1949. The development of cyanoacrylate was triggered by an accident while testing a new product. The cyanoacrylate compound bonded firmly with the prism of the refractive meter. Researchers started to focus their attention on the bonding properties of cyanoacrylate. It was manufactured as a product ten years later and since then; various manufacturers have improved and modified the methods of synthesizing the main component monomer which is the basic composition of polymers. Due to its significant characteristics, instant adhesives are widely for different applications both in the home and industries. These characteristics include:
- Instant bonding from 5 seconds to 3 minutes
- Easy to use since it does not require a curing agent
- At room temperature, strong bonds are easily achieved
- Due to its low viscosity, extremely small amounts can spread well and extend into corners to reduce the required amounts per application as compared to other adhesives
- A neat finish is easily achieved because instant adhesives are clear and colorless.
- Since it is solvent-free, virtually no shrinking is expected after curing
- Efficiency and cost effectiveness is gained during the process
Why the three-bond instant adhesive was developed
The rapid curing properties of instant adhesives are common knowledge that is why it is widely used in a good number of applications where a strong bond is required. However, there are instances when a strong bond is not immediately achieved on porous or acidic materials that include paper, wood, EPDM and polyacetal. On top this; there are many environmental issues and energy concerns that have led to higher demands in production lines.
One of the solutions to achieve this objective is the development of an adhesive that will bond within a fraction of a second which is the three-bond instant adhesive. Three-bond instant adhesives are cyanoacrylate-based liquid that can cure very quickly at room temperature since the material reacts with the moisture on the substrate to create an immediate and extremely strong bond. Since the adhesive cures even before it seeps into the pores, the product provides excellent coalescence properties for materials such as wood. Because of its unprecedented and ultra-fast adhesion properties, it significantly contributes to the efficiency of production lines. It also reduces the need for fixing jigs and the curing space required. Instant adhesives enjoy wider applications in industries like electronics and electrical because of its electrical conducting properties that are added to instant adhesion.
