An industrial adhesive is an organic or inorganic chemical compound that is used to assemble the components together. This kind of adhesive is used mostly in fastening applications such as filling the gaps between surfaces and seams to prevent leaks and infiltration of undesirable materials. It is usually classified into different ways but mostly based on its chemical composition and adhesion properties.
Classifications of industrial based on chemical composition
The common types of industrial adhesive based on chemical makeup include acrylics, cyanoacrylates, epoxy adhesives, phenolic, melamine, urea formaldehyde resins, and polyurethane. Among them, cyanoacrylates or instant adhesives are the most widely used because of their general use in bonding almost all sorts of surfaces in a very quick time possible. Conversely, acrylic adhesive is known for its outstanding environmental resistance and fast-curing abilities.
For most industrial applications, epoxy adhesives are commonly used because of their amazing properties of bonding rugged structures securely and durably. On the other hand, formaldehyde resins are thermosetting adhesives that form strong bonds and have good resistance to high temperatures. Lastly, polyurethane adhesives offer great flexibility, impact resistance, and durability, making them ideal for finishing carpentry and woodworking projects.
Categories of adhesive based on adhesion properties
An industrial adhesive is often categorized based on its bonding qualities. These include hot melt, pressure sensitive, thermoset, and UV curing adhesive. Hot melt industrial adhesives are melted through heating and set through cooling. They are ideal for assembly where parts have to be repositioned or removed. As for pressure sensitive adhesive, it is used in applications where surfaces require very slight pressure only.
Moreover, thermoset adhesive is great for high load assemblies because of its excellent creep resistance. While the last type, the UV curing adhesive is most suitable for applications that need permanent bonding without heating because it uses ultraviolet to cure the surface.
