Adhesives are extensively applied in building, manufacturing, packaging, furniture, automotive and industrial sectors. These are effective in holding surfaces together firmly without the need for mechanical fasteners like screws or bolts.
There are many different types of adhesives available today for different industries and applications. Some adhesives are designed for strong structural bonding. Others are made to be flexible, heat-resistant, or quick-setting. In this blog, we will explain what are adhesives, the different types of adhesives, their characteristics and common uses in industrial and construction projects.
What is Adhesive
Adhesives function as bonding agents which connect different materials and surfaces together. There are initially 6 types of adhesives that establish reliable and long-lasting connections which bond together metals, plastics, wood, glass and numerous other surfaces. They are commonly used because they:
- Reduce the need for welding or fasteners
- Improve production efficiency
- Provide smooth finishing
- Help distribute stress evenly
- Work on different materials and surfaces
Today, adhesives are used in industries such as construction, packaging, automotive, electronics, furniture manufacturing, and woodworking.
Types of Adhesives
Now, let’s learn about the different kinds of adhesives that are used in industrial and construction applications.
Resins
Resin adhesives are synthetic polymers used in bonding applications that require strength and durability. These adhesives can be thermosetting or thermoplastic according to their curing process.
Features Include:
- Strong adhesion
- Good resistance to chemicals
- Suitable for industries
- Strong under strain
Typical Uses: Construction, manufacturing, and woodworking
Hot Melt
Hot melt adhesives are thermoplastic adhesives that are applied in a liquid state. These adhesives cure on cooling and give a fast bonding.
Features Include:
- Fast setting time
- Simple application process
- Pretty flexible
- High speed production is suitable
Typical Uses: It is frequently used for packaging, bookbinding, paper bags and product assembly.
Anaerobic Adhesive
Anaerobic adhesives cure without air. These glues are widely used in industrial applications for tight sealing and strong bonding.
Features Include:
- High sealing capability
- Good resistance to chemicals
- Metal surfaces are suitable
- High adhesive strength
Typical Uses: Machinery parts, automotive components, and industrial fittings
Contact Spray
Contact sprays are flexible and sprayable adhesives which are used for fast and efficient bonding. These adhesives adhere well to rough and porous surfaces like wood, tiles, rubber, foam, etc.
Features Include:
- Water-resistance properties
- Flexible adhesives
- Crystal clear finish
- Easy to apply by spray
Typical Uses: Foam, furniture, laminates and decorative surfaces
Acrylic
Acrylics provide good environmental resistance and reliable bonding. They are fast-curing, high-strength structural adhesives extracted from acrylic acid. These adhesives are available in solvent-based and water-based formulations.
Features Include:
- Quick setting performance
- Weather resistance good
- Strong adhesion to the surface
- Will stand up to the elements
Typical Uses: Plastics, laminates, signage and industrial assembly
Epoxy Adhesives
Epoxy adhesives are high-strength bonding agents that are created by reacting epichlorohydrin (ECH) with bisphenol-A (BPA) to form a viscous resin, which is then combined with a hardener to initiate polymerisation. These adhesives are widely used in heavy duty industrial applications.
Features Include:
- Excellent bond strength
- Heat resistance properties
- High durability.
- Good support for load bearing
Typical Uses: Construction, automotive, aerospace, and concrete bonding
Pressure Adhesives
A pressure-sensitive adhesive bonds surfaces together with the application of light pressure. This is waterless and heatless adhesive.
Features Include:
- Easy to use
- Immediate bonding
- Flexibility of application
- Great for different surfaces
Typical Uses: Labels, tapes, packaging and printing applications
Conductive
Conductive adhesives are intended for use in applications where electrical conductivity is required. These adhesives help prevent electrostatic discharge and interference.
Features Include:
- Conductance
- Consistent electrical performance
- Good thermal stability
- Suitable for electric equipment
Typical Uses: Electronics, circuit boards, and electrical assemblies
Urethane Adhesives
Urethane adhesives provide high-performance bonding and flexibility. These adhesives are available in one pack and two pack systems.
Features Include:
- Excellent adaptability
- Good resistance to impact
- Excellent bonding performance
- Durability that lasts
Typical Uses: Furniture, construction, automotive and flooring applications
Uses of Adhesives
So, what are adhesives used for? Adhesives are employed in numerous industries to increase efficiency and deliver robust bonding solutions. Here are the common applications of these adhesives:
- Carton sealing and packing
- Furniture and cabinet work
- Automobile assembly
- Flooring and tile work
- Bookbinding and lamination
