Global aerospace interior adhesive market will register substantial gains by 2027 led by the increasing passenger air traffic and demand for lightweight aircraft. The rise in the number of air passengers globally is driving new investments in the aerospace sector as major airlines look to expand their commercial aircraft fleet. The demand for adhesives in aerospace interior applications is growing with the need to ensure greater safety and comfort of passengers.
Adhesives used for interior application in aircraft are designed to provide strong, long-lasting bonds, enhance fire resistance, and ensure the safety of passengers and crew. These formulations help maintain the interior quality of aircraft without adding any weight, thereby fulfilling both aesthetic and functional requirements. Continuous technological innovations by manufacturers to bring new, more advanced solutions to the market will bolster the aerospace interior adhesive market outlook.
Aerospace interior adhesives are typically made from epoxy resins, acrylic, polyurethane, and cyanoacrylate, among other substances. The epoxy adhesives segment is slated to witness strong growth between 2021-2027. Most adhesives used in aircraft applications are based on epoxy resins. These resins offer exceptional adhesion to a wide range of substrates, superior resistance against chemicals and corrosion, and have outstanding mechanical and thermal properties. Lower moisture absorption, the ability to be processed under a range of conditions, and robust electrical insulation are additional benefits of epoxy-based adhesives.
The market for aerospace interior adhesives in Europe will garner momentum during the forecast period 2021-2027. With the presence of some of the world’s leading aircraft manufacturers, OEMs, adhesives manufacturers, suppliers, and distributors, Europe is a major hub of the global aviation sector. The expansion of the commercial airline sector and growing military investments could offer the regional market a significant push.
Worldwide, PPG Industries Inc., Henkel AG & Company, Hexcel Corporation, Huntsman Corporation, Beacon, and Cytec Industries Inc. are among the notable manufacturers of adhesives for aircraft interior applications. These companies are collaborating with aerospace companies as part of their growth strategies to consolidate their position in the global market.
In June 2021, for instance, Henkel had collaborated with aerospace giant Boeing for the development of a new two-part epoxy adhesive, Loctite 9365FST. The adhesive is EH7S and REACH compliant globally and meets industry fire retardancy, smoke density and toxicity (FST) requirements. Back in December 2020, Hexcel Corporation had expanded its strategic partnership with aerospace contractor Safran to include advanced composite materials for a wider range of commercial aerospace applications. Hexcel has been a trusted supplier of advanced, high-performance composites such as adhesives, carbon fiber, and dry fabrics to Safran.
The global aerospace sector has suffered significant disruption due to the coronavirus pandemic, directly impacting the aerospace interior adhesive market trends. Worldwide, government restrictions and lockdown measures to curb the spread of the outbreak had resulted in a significant decline in commercial flights. Logistics and supply chain disruption due to the pandemic also posed major challenges for manufacturers.
Aircraft makers had been forced to suspend aircraft production and MRO operations, leading to a weakened product demand. Between March and April 2020, for example, Boeing had temporarily halted the production of its 737 Max and 787 aircraft due to the escalating COVID-19 situation. Combinedly, the aforementioned factors have slowed down aerospace interior adhesive industry growth to some extent. However, with the improving COVID-19 situation, ease of restrictions, and revival of the global economy, the industry will certainly bounce back in the next few years.
