_Optic adhesives Market.png
Optic adhesives fix or bond optical components—optical fibers and parts, such as prisms or lenses, displays, and glasses. These adhesives are right-transmitting and are, therefore, suitable for use in the optical path. Optical bonding is often used to optimize the optical path at the joint; however, the transmittance and the refractive index of the adhesive used must be matched to the components to be bonded. With the increased penetration of smart devices and cameras or digital cameras, the demand for optic adhesives has increased. In contrast, raw material availability and shipping difficulties are potential restraints to the increasing optic adhesives market. Growing technological innovations and new product development areas in the aerospace and medical industries are lucrative opportunities in the market.
Changing trends in the digital and defense sector
The increasing demand for deploying 5G networks for better speed and connectivity features from telecom operators is fueling the optic adhesives demand in the fiber optics application. In Jun 2022, according to the Global mobile Suppliers Association (GSA), over 794 organizations deployed either LTE or 5G private mobile networks globally. Apart from this, over 70 telecom operators are in the process of commercializing 5G services across the globe. In March 2022, the Ministry of Industry and Information Technology, China, announced that the regional telecom operators had deployed over 1.425 million 5G base stations that support over 500 million 5G users in the country. Fiber optics act as the backbone of 5G communication infrastructure. An extensive fiber optic cabling is required to interconnect 5G base stations to achieve high-speed data transmission between two locations. Such large-scale deployment of 5G telecommunication networks will increase the demand for optic adhesives in the market.
​Similarly, with the development of military systems, there are extreme reliability requirements than most commercial optical devices. Military systems sometimes have unique needs based on the field conditions they may encounter. Optomechanical adhesives used in military weapon systems must resist moisture, rain, and extreme temperatures (ie, -122°F to +176°F working temperatures for avionics; more extreme for storage), as well as thermal shock (fast temperature change) and prolonged sunlight/UV radiation exposure. Free radicals can be generated by UV exposure, which often requires free-radical scavengers and antioxidants to be included in the adhesive formula. It creates a moment for manufacturers to burrow into a new market.
​Furthermore, fiber optics are widely used in various military applications that require reliability and performance in operations—from tactical military communication systems to terrain vehicles. They are used to establish communication between military bases and shelter hospitals. Installing fiber optics in various military systems, such as tactical military communication systems, terrain vehicles, and weapon systems, has become essential. Advances in fiber optic technology have led to a hike in demand for fiber optics in military applications. For instance, wavelength division multiplexing technology can transmit digital and analog signals faster than previous communication systems. These advances in the fiber optics market have given rise to new opportunities for optic adhesives in military applications, including communications, sensors,
Trends in smart devices and camera or digital sensors
Rising demand for smart devices, tablets, ADAS systems in the automotive industry, computers, display screens of medical devices, television sets, and LCD screens is driving the market. Optic adhesives bind a transparent layer in these devices to protect them from harsh chemicals, damage, and scratches. They also help improve the mechanical, optical, and electrical performance of the display module and device, as well as its viewability, readability, and contrast in indoor and outdoor devices.
​Along with the smart device's penetration, sensors are establishing their strong presence in the digital world. These sensors serve different purposes, such as biometric devices, health monitoring devices, automotive applications, aerospace applications, forced arms, and others. Devices must be lightweight and rigid in their structure to serve the requirements. Optic adhesives come into the picture to meet such demands as they are specially designed to maintain internal stress. help in meeting all these needs, which, in turn, increases their demand.
