There are plenty of reasons why an industrial adhesive is chosen over mechanical fasteners. First of all, these adhesives can be used for a wide variety of assembly applications. More importantly, they will not cause damage to the substrate by drilling the holes for attachment and they do not need heat distortion. Furthermore, you can use the adhesive to assemble different materials without causing any galvanic corrosion. It also offers a higher fatigue resistance for the joined parts by not concentrating stress at only a few localized spots. Lastly, the use of industrial adhesives doesn’t leave behind protrusions or needs further refinishing so you’ll have a more pleasing finish product.
In addition, industrial adhesives are categorized according to their chemistry. They are even capable of bonding metal with overlapping shear strengths of more than 1,000 psi with room temperature. They are usually classified based on cyanoacrylate, acrylic, urethane or epoxy chemistries. There are also some hybrids available to consider if your unique application needs it. Each of the industrial adhesive types can be customized to some extent like incorporating diluents to reduce the viscosity or thickeners to increase it. Though these adhesives are comparable according to their general properties, it is still crucial to carefully consider the specific properties inherent to the specific chemistry of the adhesive.
When selecting the right industrial adhesives, there are some general principles to follow. Though you can talk with the technical engineers or consultants for some knowledge, preliminary decisions are still important before discussing the case with others. On top of the considerations required to choose the most appropriate industrial adhesive is the application performance and its requirements. After these factors have been determined, then you can proceed with selecting the right adhesive type that fits those requirements in the most economical way. Ultimately, whatever kind of adhesive you select initially, it must be tested first before you finally decide which one to use.
