What is synthetic adhesive and what is its use?

Synthetic adhesive is a type of adhesive that is made from synthetic materials, rather than natural materials like plant or animal products. Synthetic adhesives are typically made from polymer resins, which are long chains of molecules that can be moulded or shaped into a variety of forms.

Synthetic adhesives are known for their strength, durability, and versatility, and they are widely used in a variety of industries, including construction, automotive, and aerospace. Some examples of synthetic adhesives include epoxy, polyurethane, and acrylic adhesives. The main advantage of synthetic adhesives is their ability to stick to any surface with a smooth surface. The most popular synthetic adhesive is epoxy resin, which has been widely used for years in the automotive industry.

Classification of Adhesives

In the case of synthetic adhesives, this is the primary raw material. Not only does it affect the reaction of the adhesive to heat but also determines the physical and mechanical characteristics like water resistance, chemical resistance, load bearing capacity, abrasion resistance, and the flexibility.


The glue ingredients in thermoplastic systems comprise the polyvinyl acetate, nitrocellulose, polypropylene, vinyl acetate-ethylene copolymer Polyethylene, polyesters polyamides, acrylics and cyanoacrylates. These polymers are also utilised for hot melt glues which offer a cleaner solvent-free option.

Thermosetting systems

Thermosetting adhesive chemistry employs the raw materials like polyurethane, epoxy formaldehyde, unsaturated polyesters , and formaldehyde from phenol. The thermosetting systems made of epoxy resin are usually considered to be the most durable. If a more flexible and flexible system is desired, polyurethane can make the best option.

Elastomeric adhesives

In addition to thermoplastic and thermoset adhesives, there are elastomeric systems that can function in any of the previously mentioned polymer types based on the type of adhesive needed to cross link. Elastomeric adhesives are quick to assemble and have a high degree of flexibility. They are also easy to alter and flexible when used. The materials that make up the adhesive for Elastomeric systems include the natural rubber and butyl rubber butadiene rubber, silicone Nitrile rubber, neoprene and styrene rubber.

Pros and Cons of Synthetic Adhesive

There are several pros and cons of synthetic adhesives to consider:


  • Synthetic adhesives are generally very strong and durable, and they can be used to bond a wide range of materials.
  • They have good resistance to water, heat, and many chemicals, making them suitable for use in a variety of environments.
  • Synthetic adhesives can be precisely formulated to meet specific performance requirements.
  • They can be easily applied using a variety of techniques, such as spraying, spreading, or injecting.


  • Synthetic adhesives may be more expensive than natural adhesives.
  • Some synthetic adhesives may have a strong smell or produce hazardous fumes when they are applied or cured.
  • Some synthetic adhesives may not be suitable for use with certain materials, such as certain plastics or rubbers.
  • They may not be as environmentally friendly as natural adhesives, as they are made from synthetic materials that may not be biodegradable.

How to check the best Adhesives

The compound which we use for making synthetic adhesives should satisfy certain criteria in order to serve its purpose of connecting two bonds. There are a few factors to consider when choosing the best adhesive for a particular application:

  1. Compatibility: Make sure that the adhesive is compatible with the materials you want to bond. Some adhesives may not work well with certain materials, such as plastics or rubbers.
  1. Strength: Consider the strength of the adhesive and whether it is suitable for the type of load that the bonded joint will need to withstand.
  1. Resistance: Think about the environment in which the adhesive will be used and whether it needs to be resistant to water, heat, or chemicals.
  1. Cure time: Consider the cure time of the adhesive and whether it is suitable for your needs. Some adhesives cure quickly, while others may take longer.
  1. Cost: Compare the cost of different adhesives to determine the best value for your application.

It may be helpful to test a small sample of the adhesive on the materials you want to bond before committing to using it for a larger project. This will allow you to see how well it works and whether it meets your needs.


What are the uses of Synthetic Adhesives?

  • Synthetic adhesives are used in a wide range of applications, including bonding, sealing, and coating.
  • They are used in the construction industry to bond building materials, such as concrete, brick, and wood.
  • They are also used in the automotive industry to bond car parts and in the aerospace industry to bond aircraft parts.
  • Synthetic adhesives are used in the manufacturing of products such as shoes, furniture, and packaging materials.
  • They are also used in the medical field for wound closure and in the electronics industry for circuit board assembly.
  • Synthetic adhesives are known for their strength, durability, and versatility, and they can be used in a variety of temperature and humidity conditions.

Synthetic adhesives are utilised in two categories:

  1. Industrial use

Synthetic Adhesives are used in every kind of industry whether heavy or small. In smaller industries, such as those that deal with food items and stationery products, as well as toys adhesives play a significant part in the processing of packaging. In small-scale industries, it is used for tasks such as connecting the components of toys, and the lipstick being connected with its foundation.

In the heavy industry, it is used for the assembly of spare parts for any vehicle or machine, painting cars or marking the parts by using labels. Furniture woods are joined to strong adhesives and in construction industries too to ensure durability in structures. In addition, there are many more applications for adhesives.

  1. Personal use

In everyday life, there are a variety of applications for adhesives, which ranges from sticking envelopes , to joining any damaged materials. In this regard, glue happens to be the one most commonly used type of adhesive on a regular basis. The type of glue is the glue stick, cello tapes, gum repair of shoes, to glue postage stamps, and to pack gifts
