We invite you to visit Rongcheng together on April 16th! Paralon showcases aerospace grade Parylene coating technology at the 2026 Chengdu National Defense Technology Exhibition

The highly anticipated 2nd Chengdu Defense Science and Technology Industry Expo will grandly kick off at the Chengdu Century City New International Convention and Exhibition Center from April 16th to 18th, 2026. As a leading provider of Parylene special coating technology services in China, Shanghai Paralon New Materials Co., Ltd. will showcase its core technologies and products at booth E06-3 in Hall 2. We sincerely invite customers from all over the country to gather in Rongcheng to explore the infinite possibilities of aerospace protective coating technology.
Born for aerospace, creating a legendary protective coating
Parylene, This protective coating material, which is now flourishing in many fields, has always been closely related to the aerospace industry in terms of its birth and development. In the 1960s, William Gohan, a scientist at Union Carbide in the United States, successfully developed Parylene vacuum deposition film technology to solve the severe protection problems of electronic components in the aerospace field. At that time, spacecraft faced multiple challenges such as sudden temperature changes, strong radiation, and high vacuum in extreme environments. Traditional coating materials were either heavy and affected equipment lightweighting, or had insufficient protective performance to resist complex environmental erosion. The emergence of Parylene broke this deadlock. It uses p-xylene compound as raw material and can form a uniformly thick, dense and pinhole free transparent film on the surface of the component at room temperature through vacuum vapor deposition process. This feature perfectly meets the ultimate requirements of protective coatings for aerospace electronic equipment, and Parylene has naturally become the designated protective coating for US military printed circuit boards, aerospace and underwater launch device microelectronic components. In 1972, it was included in the US military standard MIL-I-46058C, opening its legendary journey in the field of high-end protection.
Aerospace grade performance, empowering the upgrade of aerospace equipment
After decades of technological iteration and innovation, the application value of Parylene coating technology in the aerospace industry has become increasingly prominent, especially in core requirements such as lightweight, high dielectric, and three proof, demonstrating irreplaceable advantages. In terms of lightweighting, aerospace equipment pays close attention to every weight, and weight reduction means longer range, higher payload, and better performance. The Parylene coating thickness of Paralon can be precisely controlled between 0.1 μ m and 100 μ m. The ultra-thin coating thickness hardly adds extra weight to the equipment, but provides comprehensive protection. Whether it is precision sensors, complex integrated circuits, or tiny MEMS devices, Parylene coating can provide a layer of “invisible protective clothing” for them without affecting the original structure and performance of the equipment, perfectly balancing protection and lightweight requirements. High dielectric performance is one of the core indicators of aerospace electronic equipment. The Parylene coating of Paralon has an extremely low dielectric constant and excellent dielectric strength, which can effectively reduce signal transmission losses and improve the operational stability and reliability of electronic devices. In equipment such as airborne radar and phased array radar that require extremely high signal transmission, Parylene coating can serve as a high-performance insulation layer to ensure clear and accurate signal transmission in complex electromagnetic environments, providing strong support for the precise operation of aerospace equipment. In terms of moisture resistance, mold resistance, and salt spray resistance, Parylene coating from Paralon performs exceptionally well. Aerospace equipment often needs to work in harsh environments such as high temperature and humidity, salt spray corrosion, and mold growth for a long time. Traditional protective materials are difficult to resist the erosion of these complex environments. The Parylene coating, with its dense and pinhole free structure, can effectively block the invasion of harmful substances such as water vapor, salt, and mold, providing equipment with protection for decades. Even in extreme environments such as coastal areas and high altitudes, electronic devices protected by Parylene coating can still operate stably, greatly improving their environmental adaptability and service life.

Technological innovation leads the new direction of industry development
As a specialized and innovative enterprise in Shanghai, as well as a technology-based small and medium-sized enterprise, Paralon has been deeply involved in the Parylene special protection field for more than ten years, always adhering to a market-oriented approach and continuously promoting technological innovation and upgrading. The company has a three-level clean room and has passed multiple quality system certifications such as AS9100D, ISO9001, GJB9001C, etc. The core equipment and materials are fully self-developed, with 50 national patents, including 34 invention patents, and has led the development of industry standards for Parylene coatings. In response to the constantly evolving protection needs in the aerospace industry, Parylene composite coating technology developed by Paralon not only retains the advantages of traditional Parylene coatings, but also further enhances the performance of low surface energy substrate adhesion and low high-frequency loss. At the same time, it has the characteristics of nano micron ultra-thin, low gas release, anti-bacterial, and anti metal whisker. This technology has been successfully applied to multiple aerospace projects, providing reliable protection for key components of equipment such as satellites, missiles, and drones. Some of the technologies have even filled domestic gaps.
Sincerely invite to gather and discuss new opportunities for cooperation
Currently, the aerospace industry is rapidly developing towards integration, miniaturization, and intelligence, and the requirements for protective coating technology are also increasing. Thanks to its profound technical accumulation, excellent product performance, and rich application experience, Paralon has become an important participant in the field of aerospace protective coatings. At the 2026 Second Chengdu Defense Technology Industry Expo, Paralon will not only showcase its latest achievements in Parylene coating technology, but also have in-depth exchanges with merchants from all over the country to explore the development trends and cooperation opportunities of aerospace protective coating technology. We sincerely invite industry colleagues, experts, scholars, and buyers to visit booth E06-3 in Hall 2 to experience the unique charm of Parylene coating technology up close, discuss cooperation plans, and work together to promote the innovative development of aerospace protective coating technology. In April, Rongcheng is full of spring. Let’s gather at the Chengdu Century City New International Convention and Exhibition Center to attend this feast of national defense technology and open a new chapter in aerospace protective coating technology!
