Glue is widely used in every sector for a variety of applications. In earlier times, glue was extracted from plants naturally. However, glues are now manufactured according to the usage category. Mostly they are extracted from animal by-products like collagen & cooked at high temperatures.

Introduction

Ever wondered what goes into making the sticky stuff that keeps things together and what adhesives are made from? 

Glue is an adhesive that has been used for generations, Its manufacturing method has progressed from initially using natural sap to now developing specialised synthetic ingredients. 

This blog will dig into the intriguing world of glue manufacturing. It will investigate the raw ingredients, equipment, and methods used to produce this multipurpose substance. 

This will give essential insight into the vast and intricate world of glue creation. This is whether you’re a DIY enthusiast or simply curious about the production process. 

The earliest and oldest glue dates back to 200,000 years ago and historically was made from fish. 

How Is Glue Made?

Glue is a common substance used to join two surfaces together. Glue production involves several procedures and numerous raw materials. 

Natural or synthetic raw materials, or a combination of the two, can be utilised to manufacture glue.

Animal by-products such as bones, cartilage, and skins are natural sources of raw materials used in adhesive manufacturing. These materials are cooked to extract collagen, the main constituent in animal-based glue. 

Plant extracts such as soybeans, cornflour, and potato starch can also make vegetable-based glues.

Manufacturing Process of Synthetic Gum and Super Glue

Petroleum-based products like polymers and resins, on the other hand, are synthetic sources of raw materials utilised in glue synthesis. 

These synthetic materials are extensively used in manufacturing adhesives, such as cyanoacrylate glue, sometimes known as “super glue” due to its quick bonding capabilities.

Manufacturing adhesives is mainly based on the type of glue being manufactured. Animal-based glue, for example, is manufactured by boiling animal by-products until the collagen is removed, then adding water and other chemicals to make the finished product. 

Synthetic adhesives are made by a chemical reaction process that requires mixing raw components in a specified order and under specific circumstances. This is to produce the required glue.

Ingredients Used in Making Glue

Solvents, preservatives, and thickeners are popular glue ingredients. Preservatives are added to the glue to increase its shelf life, while solvents break down the basic components and make them easier to work with. Thickeners are additives that change glue viscosity to make it simpler to apply.

The Fevicol Manufacturing Process

Fevicol manufacturing takes place in different steps, from making adhesives to processing, packaging, and sending cartoons. 

1. Manufacturing of Fevicol Adhesive

In India, Fevicol is a well-known adhesive brand associated with glue. Because of its high bonding strength, glue is the adhesive used in furniture manufacturing. 

Fevicol is manufactured through a sequence of procedures that include mixing, processing, and packaging.

Natural and synthetic sources of sticking materials are employed to manufacture Fevicol. 

The raw material for Fevicol is a petroleum-based resin combined with a solvent and a hardener to form the adhesive. 

Other ingredients, such as stabilisers and thickeners, may be added to the mixture to change the adhesive’s characteristics.

2. Mixing, Processing, and Packaging

Resin, solvent, and hardener are mixed in an enormous tank to begin adhesive manufacturing. To ensure the components are thoroughly integrated, the mixture is heated to a specified temperature and stirred. 

To complete the process, the fluid is cooled and transported to a storage tank for further processing.

Filtering the glue to eliminate impurities is the next stage in the production process. The glue is further treated to acquire the necessary consistency and viscosity. 

Thickeners are used to make the glue more viscous, while stabilisers are used to ensure adhesive qualities remain stable over time.

After the glue has been treated and stabilised, it is moved to a packaging line and poured into various-sized containers. After that, the containers are labelled and packed for shipment.

Introduction to Adhesives, Glues, and Sealants

Adhesives, glues, and sealants are crucial materials for joining and bonding. While these names are used interchangeably, they refer to separate categories of products, each with its own characteristics and uses.

Adhesives are chemicals used to join two or more materials together. They function by filling gaps between surfaces and forming a strong connection. Adhesives are classified into two types: reactive and non-reactive. 

Non-reactive adhesives are connected by physical processes such as evaporation or cooling, whereas reactive adhesives require a chemical reaction to attach the components.

Differentiating Glue, Adhesive, and Sealant

Glue 

Adhesive 

Sealant

Primarily composed of  natural or synthetic polymers and can be water-based or solvent-based.

Composed of resins and solvents, and wetting agents.

Contains an elastomeric compound for flexibility together with a filler product. 

Conversely, glue is a form of glue widely used in woodworking, crafting, and regular household maintenance. They are composed of natural or synthetic polymers and can be water-based or solvent-based. 

Glues are intended to provide a robust and permanent bond between two materials.

Meanwhile, sealants are compounds that provide a barrier between two surfaces to restrict the passage of air, water, or other materials. 

They often cover gaps, joints, and fractures in construction, automotive, and plumbing applications.

Adhesives come in various varieties, each with unique properties and applications.
