Adhesives mostly have the same basic properties; however, there are numerous types of adhesives, each of which can be differentiated by their specific characteristics. Some of the characteristics by which adhesives are commonly classified and categorized include:
Thermosetting adhesives do require a curing period. When the thermoset adhesive is first applied to a substrate, they have short polymer molecules. During the curing process, the thermoset adhesives undergo a chemical cross-linking reaction, which is irreversible, and thus bonds together long chains of polymer molecules. Due to this reaction, the physical properties and chemistries of thermoplastic adhesive changes, and thus allowing the adhesive bond to set.
Thermoplastic adhesives don’t require a curing period as thermoset adhesives require. Once the adhesive is applied, it either cools (in case of hot melt adhesives) or dries (in case of glue) to form an adhesive bond between two substrates.
Today adhesives offer a solution to replace traditional screws and nut-bolts and also used to join similar and dissimilar substrates. The benefits of using adhesives are:
Adhesives have numeral advantages over other materials or techniques, but also it presents several drawbacks and disadvantages, and they are:
In the adhesives market, the significant players are:
The growing trend of lightweight and low carbon-emitting vehicles, growing construction industry are the major driving factors due to which the adhesives are gaining the market share.
