Any substance that is applied to one surface (the substrate) and creates an attraction between it and another surface is referred to as an adhesive. Because most adhesives are polymeric, they adhere through mechanical mechanisms, such as molecular bonding (e.g., covalent bonding). Additives (for example, plasticizers) can enhance the binding by increasing interfacial shear strength. Furthermore, many conventional adhesives are made with environmentally benign processes and hence have no negative effects on the environment.
Glue, tape, mucilage, and paste are the most popular industrial adhesives. Cement (used in masonry), chewing gum, double-sided tape, and epoxy resin glues used in electronics manufacturing are examples of other forms.
The function of many high-tech items is dependent on special adhesives. Super glue, for example, is commonly used in orthopaedic surgery and dentistry; it's also found inside some athletic shoes to provide more traction on a wet or slick playing surface.
Fevicol and its derivatives are the most widely used home items in India, with the Fevikwik form being one of the world's most widely used adhesives. If you want to develop your own adhesive company, Fevicol can be used as a basis product to create your own unique variations. Fevicol and other adhesives are extremely versatile and can be utilised in a wide range of industries.
Although natural adhesives are less expensive to manufacture, synthetic adhesives are the most used. Synthetic resins and rubber-based adhesives excel in terms of adaptability and performance. Synthetics can be manufactured in a consistent supply with consistent qualities. Furthermore, they can be adjusted in a variety of ways and are frequently combined to provide the greatest qualities for a given application.
The thermoplastics and thermosets are the two types of polymers utilised in synthetic adhesives. At normal temperatures, thermoplastics provide strong, long-lasting adhesion, and they can be softened for application without degrading. Nitrocellulose, polyvinyl acetate, vinyl acetate-ethylene copolymer, polyethylene, polypropylene, polyamides, polyesters, acrylics, and cyanoacrylics are some of the thermoplastic resins used in adhesives.
Unlike thermoplastics, thermosetting materials generate permanent, heat-resistant, insoluble connections that cannot be adjusted without deterioration. The aerospace sector makes extensive use of adhesives made of thermosetting polymers. Phenol formaldehyde, urea formaldehyde, unsaturated polyesters, epoxies, and polyurethanes are examples of thermosets.
• Carpenters rely heavily on various adhesives to do their work. Yellow Wood Glue, for example, is formed of vinyl acetate and is usually water-based.
• Lightweight materials such as cardboard, paper, cloth, and children's crafts require adhesives such as white craft glue. Water is usually their carrier, making them easier to clean and less dangerous. Before any strength can be detected, these types of glue must cure.
• Glue sticks are fantastic for stationery use, especially for children. They provide a low-bonding glue with long-lasting results. These glues work on a variety of papers, including cardboard, poster board, and foam board. The adhesive usually dries transparent. The sealing of envelopes is a good example of where they can be used.
• Adhesive is commonly used in the textile sector. Fabric adhesives, such as liquid white glues like polyvinyl acetate, can be used in this way.
• Acrylate adhesives are commonly used in the ceramic and leather industries. These glues tend to join quickly and provide a strong connection with a clear finish.
• Adhesive is used in the paint industry to improve paint and coating adhesion.
Market Size in India:
India's adhesives industry has grown to become one of the world's major users of adhesives, thanks to the rise of numerous end-user sectors. By the end of 2020, India's adhesives industry is estimated to be worth roughly USD 5.7 billion. The India Adhesives market is predicted to increase at a significant rate over the forecast period, according to Researcher.
Increasing demand for adhesives and sealants in a variety of end-user sectors, such as automotive and construction, as well as technological developments in formulations, are two main factors propelling the market forward.
Adhesives are widely used in the construction industry because of their important characteristics and physical properties, such as high cohesive strength, good adhesion and elasticity, flexibility, cohesion, and environmental resistance to UV light, corrosion, salt water, rain, and other weathering conditions, as well as the substrate's high elastic modulus and thermal expansion resistance.
Over the projection period, the Indian construction industry is expected to increase at a rate of approximately 15%, reaching around USD 800 billion. In India, there are almost 20,000 active construction projects. Furthermore, the United Nations estimates that India's urban population would grow from 377 million in 2011 to 594 million in 2036, representing a 57 percent increase. The rise of the building industry in the region is primarily due to rapid urbanisation.
The rise of the industrial adhesives market has been aided by growth in the packaging, building & woodworking, and transportation end-use industries, as well as technical improvements. Between 2015 and 2021, the industrial adhesives market increased at a CAGR of 4.8 percent.
Bio-based alternatives are being created as a result of rigorous environmental restrictions. The key bio-based adhesives that will see increased sales and production over the forecast period are soybean-derived polyols, vegetable oil-based polyamides, polyisoprenes, and epoxies. The market is estimated to increase at a CAGR of 5% over the forecast period. (2022-2032).
Adhesives are widely used in the construction sector, which includes both residential and non-residential building. The building business in Asia Pacific is steadily growing as the region's urbanisation and people's living conditions improve. Due to increased industrialisation and residential and commercial construction activity in Asia Pacific, the adhesives industry is quickly rising. Adhesives are used in a variety of ways in the construction industry. Ceramic tiles, concrete, flooring underlayment, pre-finished panels, and roofing are just a few examples.
The worldwide building and construction sector is influenced by macroeconomic trends as well as political actions. Industry participants are encouraged to embrace sustainable designs and green building techniques as a result of quality improvements and LEED certification. As a result, the demand for adhesives rises. The growing need for adhesives in green building technology has increased the need for R&D to produce new adhesive materials.
