Adhesives are compounds that are used to adhere or bond two items together so as to form a single unit. It can be obtained from natural as well as synthetic sources. On the other hand, sealants are materials that are used to prevent leakage of fluids from containers, thus providing a leak proof barrier. Adhesives and sealants have large application in aerospace industry apart from construction, packaging, automotive, and consumer products. Aerospace adhesives and sealants can be of different types based on resins such as Epoxy, Benzoxazine, Bismaleimide, thermosetting acrylic, and others. Adhesives and sealants have large application in structural building of aircrafts. They form surface attachment through adhesion. Adhesives and sealants are largely used in aerospace industry to provide shear and tensile strength between parts/structure. They usually have high shear strength (over 1,000 pounds per square inch or psi). There are several internal and external factors that determine the success of the bonding or sealing operation. Factors such as chemical exposure, weathering, light, oxidation, moisture, temperature have imperative impact on adhesives and sealants functionalities.
Adhesives and sealants market is significantly penetrating in the aerospace industry. Rising demand for ultra-light and ultra-compact carrier vehicles in military operations, increasing air travelling activities in emerging countries, and entry of new airliners has bolstered the demand for aerospace adhesives and sealants. However, increasing carbon emission due to rise in air travelling would hamper adhesives and sealants market. Additionally, regional government has imposed several environmental regulations regarding VOC emission which in turn hinders growth of aircrafts and thereby aerospace adhesives and sealants. Development of bio based aerospace adhesives and sealant is expected to exhibit a promising market in the future.
The Asia Pacific region is expected to be the fastest growing segment in the aerospace adhesives and sealants market. The growth of aerospace adhesives and sealants in this region is mainly attributed to the high economical growth rate followed by increasing demand for commercial aircrafts which eventually driving the aerospace industry. The RoW market is projected to show a rising growth in the next six years with allied industries expected to showcase a stable growth. Countries such as China, India, Russia, Germany, Australia and Japan are anticipated to persist as a strong emerging aerospace adhesives and sealants market. Furthermore, there are several global events such as Olympics, Cricket World Cup which are scheduled for the coming years and is going to be hosted by emerging regions. This would increase movement of people from one region to other, and as a result airliners would introduce new aircraft which in turn would increase demand for aerospace adhesives and sealants. Moreover, several ongoing space exploration programmes is expected to boost demand for aerospace adhesives and sealants in the foreseeable future.
Research and development is crucial part of aerospace adhesives and sealants market. The suppliers, manufacturers, and association infuse high investments in product development, support, and technology to meet the need of various other end-use industries. Market leaders are investing continuously to develop innovative materials to provide practical, economical, and performance benefits to customers. For instance, in January 2014, Huntsman Corporation introduced new adhesives product in their benzoxazine and epoxy resins product portfolio. Epibond 300 A/B epoxy adhesive, which is a high-strength liquid shim adhesive, has primary applications in aerospace and metal industries.
There are several players in the aerospace adhesives and sealants market. Some of them include BASF SE, Henkel Corporation, The 3M Company, H.B. Fuller, The Dow Chemical Company, Cytec Industries Inc., Master Bond, and PPG Industries.
