Metal bonding adhesives are used to attach metal-to-metal surfaces in various end-use industries such as automotive and transportation, industrial and others. These adhesives have high strength, low odor and rapid cure speed. These adhesives can be easily applied over the metal surface via static mixer. They absorb thermal shock and expansion stress and are non-flammable, thereby increasing the growth of the metal bonding adhesives market.
Metal bonding adhesives are categorized into epoxy-based, acrylic-based, polyurethane-based, silicon-based and modified phenolic resin. Epoxy-based adhesives are used for metal bonding, owing to their durability, high strength, temperature resistance and depth of cure. These adhesives are known as Crash Durable Adhesives (CDA), as they encompass superior bonding properties resulting into improved crash resistance. Hence, epoxy-based adhesives are widely preferred in manufacturing lightweight automotive parts. Acrylic-based, used for permanent bonding assemblies, are based on acrylic polymers. Acrylic-based adhesives have high impact strength, high adhesion and bond strength equivalent to that of epoxy-based adhesives. These adhesives are mainly used as anaerobic adhesives in industrial applications.
Metal bonding adhesives are used in industrial applications as an alternative to traditional bonding methods for heat treatment and fastening. They are also widely used in industrial applications, including ultra-centrifuge rotors, machinery-based plates, cooling water pumps, reaction injecting molding machines, cooling water pumps and industrial pumps. These adhesives are utilized by the healthcare industry for bonding applications in dialysis machines, filters, needle bonding and X-ray and imaging equipment. Metal-to-metal bonding applications in the construction industry such as scrapers and trenchers are considered under the industrial segment.
The global metal bonding adhesives market is expected to witness significant growth during the forecast period (2017-2023). Stringent government regulations to enhance the fuel economy coupled with increasing growth of the automotive, pharmaceuticals and mining industries are the factors estimated to propel the growth of the global metal bonding adhesives market.
Based on resin, the epoxy-based is expected to be the largest growing segment in the global metal bonding adhesives market during the forecast period. Military and defense is expected to be the largest growing market in the global conductive textiles market. Additionally, automotive and transportation is projected to be the largest application segment of the metal bonding adhesives market during the forecast period.
The key trend projecting growth in the metal bonding adhesives market is the rising focus of the automotive industry to produce lightweight vehicles without increasing the cost or penalizing on performance, quality and safety. This is obtained by replacing or reducing the usage of welding, bolts, screws, spot welding and other attachments by metal bonding adhesives. Additionally, the increasing demand from countries such as Canada and the U.S is further bolstering the growth of the global market during the forecast period.
The key factors driving the growth of the global metal bonding adhesives market are stringent government policies towards enhancement of fuel economy and growth in automobile, pharmaceuticals and mining industries. The steady rise in GDP has increased the adoption of adhesives in automotive applications thereby, boosting the growth of the metal bonding adhesives market. Additionally, easy availability of raw materials globally and adoption of development strategies to meet the growing demand for metal bonding adhesives are propelling the growth of the market.
Metal bonding adhesives are gaining traction from the automotive and transportation industry owing to their increased usage from Original Equipment Manufacturers (OEMs) for automotive exteriors and panel bonding. These adhesives find application in bonding body panels of buses and trucks.
Asia-Pacific region is estimated to be the largest region for the metal bonding adhesives market owing to the increased industrial growth in the countries such as India, Vietnam, Indonesia and Thailand. Additionally, increased investments in chemicals, petrochemicals, oil and gas and food and beverages industries is expected to further spur the growth of the global metal bonding adhesives market. Increase in investments made by companies in the automotive sector coupled with the shift of production facilities to emerging economies and strong industrial base are additional factors contributing to the growth of the market in the Asia-Pacific region.
The key restraints hampering the growth of the global market for metal bonding adhesives is the time required for the fixation of bonding tapes and development of the entire product; however, the time required for the fixation of bonding tapes during the development of the product can be reduced.
