When Are Adhesives Used?

Adhesives are a group of materials that have the property of sticking to surfaces of different materials. They are widely used in industries such as construction, automotive, and packaging, among others. Adhesives are essential in the production of various items, including aircraft, boats, vehicles, and furniture. In this article, we will discuss the different types of adhesives and when they are commonly used.

Types of Adhesives

Adhesives are classified according to their chemical composition, curing mechanism, and physical properties. Here are the five main categories of adhesives:

1. Cyanoacrylate Adhesives

Cyanoacrylate adhesives, commonly known as superglue, are a type of fast-acting adhesive with excellent bonding strength. They are used in various applications, including bonding of non-porous materials, like metal, plastic, and glass.

2. Epoxy Adhesives

Epoxy adhesives are used in high-stress applications, bonding metals, concrete, and fiberglass, among others. They have a slow curing time, which allows for adjustment of the bonding surfaces to achieve perfect alignment. Epoxy adhesives have excellent chemical resistance and are ideal for use in harsh environments.

3. Silicone Adhesives

Silicone adhesives are used in high-temperature applications, where other adhesives would fail. They remain flexible over a wide temperature range, making them suitable for use in sealing and bonding electronic components and automotive parts.

4. Polyurethane Adhesives

Polyurethane adhesives are used in the construction industry, bonding items such as flooring, wooden structures, and insulation. They bond well to a wide range of materials, including concrete, stone, and metal. Polyurethane adhesives create strong, long-lasting bonds with excellent all-weather resistance.

5. Acrylic Adhesives

Acrylic adhesives have excellent bonding strength, making them suitable for use in bonding & assembling metal, plastic, and composite materials. They have a fast cure time, making them ideal for high-speed production.

When Are Adhesives Used?

Now let us look at some common applications of adhesives.

1. Automotive Industry

Adhesives are commonly used in the automotive industry to join different parts of a vehicle. Cyanoacrylate adhesives, for example, can be used to fix small parts or adhere the rearview mirror to the windshield. Epoxy adhesives are ideal for bonding engine parts, like pistons and engine blocks, where high strength is required. Polyurethane adhesives are used to seal car body joints and attach windshields.

2. Construction Industry

Adhesives are widely used in the construction industry for bonding a variety of materials, from metal to concrete. Acrylic adhesives are ideal for bonding metal and composite materials, while polyurethane adhesives are used in the construction of wooden structures, like stairs, flooring, and roofs. Epoxy adhesives are used in bonding concrete, fiber-reinforced polymers, and steel structures.

3. Aerospace Industry

The aerospace industry uses adhesives in manufacturing aircraft due to their ability to reduce weight while maintaining strength. Large aircraft parts, such as wings and fuselage, are constructed with adhesive bonding. Cyanoacrylate adhesives are used to bond small aircraft parts, such as window seals.

4. Electronics Industry

Adhesives are widely used in the electronics industry to fix and protect electronic components, like circuit boards and sensors. Silicone adhesives are ideal for sealing and bonding electronic components due to their excellent high-temperature resistance.

5. Packaging Industry

The packaging industry uses adhesives to assemble cardboard and packaging materials. Cyanoacrylate adhesives are ideal for sealing small packages, such as envelopes, while hot melt adhesives are used for carton sealing.


Adhesives are used in a wide range of industries due to their excellent bonding properties. Various types of adhesives have different strengths and are suitable for different applications. If you are planning to use adhesives, consider factors such as the application, bonding surfaces, and environmental conditions. Furthermore, make sure you choose an adhesive that is compatible with your application and follow the manufacturer's instructions for optimal adhesion.
