How to optimize the formula of coating absorbing materials to improve their comprehensive performance

In the current era of rapid technological development, the importance of coating absorbing materials in many fields is becoming increasingly prominent. Both the stealth requirements in the military field and the suppression of electromagnetic interference in the electronic communication industry have placed strict demands on the comprehensive performance of coating absorbing materials. As an innovative pioneer in the industry, Advanced Institute (Shenzhen) Technology Co., Ltd. has been committed to improving the comprehensive performance of coating absorbing materials through optimized formulations, providing high-quality products and solutions for various industries.

Accurate screening and matching of absorbing fillers

Absorbing filler is the core component that determines the absorbing performance of coatings. Advanced Institute (Shenzhen) Technology Co., Ltd. conducts in-depth research on the characteristics of various types of absorbing fillers, and accurately selects and matches them according to different application scenarios and frequency band requirements.

Metallic absorbing fillers such as carbonyl iron powder have high electrical conductivity and can effectively dissipate electromagnetic wave energy through electronic conduction, exhibiting good absorbing effects in specific frequency bands. Ferrite materials, such as barium ferrite and strontium ferrite, absorb electromagnetic waves over a wide frequency range due to their unique magnetic loss characteristics. Carbon based absorbing fillers, such as graphene and carbon nanotubes, bring new possibilities for improving absorbing performance due to their low density, high specific surface area, and excellent electrical properties.

In actual formula design, Advanced Institute (Shenzhen) Technology Co., Ltd. cleverly combines different types of absorbing fillers through extensive experiments. For example, by combining carbonyl iron powder with barium ferrite, the excellent absorption performance of carbonyl iron powder in the high frequency range is utilized, combined with the stable performance of barium ferrite in the mid low frequency range, to broaden the absorption frequency band of the coating. At the same time, precise control of the content of absorbing fillers ensures the balance of other coating properties while achieving efficient absorption.

Carefully selected and modified matrix resin

The matrix resin, as a carrier for absorbing fillers, plays a crucial supporting role in the mechanical and weather resistance properties of coatings. Advanced Institute (Shenzhen) Technology Co., Ltd. is extremely meticulous in the selection of matrix resins.

Epoxy resin has become the preferred choice for applications with high mechanical performance requirements, such as aircraft stealth coatings in the aerospace field, due to its excellent adhesion, high strength, and good chemical corrosion resistance. Polyurethane resin performs well in absorbing coatings for automotive, outdoor electronic devices, and other fields due to its excellent flexibility, wear resistance, and weather resistance. Acrylic resin is widely used in some projects that require construction efficiency due to its fast drying speed and good construction performance.

In order to further enhance the compatibility between the matrix resin and the absorbing filler, as well as the comprehensive performance of the coating, Advanced Institute (Shenzhen) Technology Co., Ltd. will also modify the matrix resin. By introducing specific functional groups or additives, the performance of the resin can be improved, enabling it to work better in conjunction with absorbing fillers and enhance the overall performance of the coating.

Reasonably add functional additives

Functional additives are being optimizedCoating absorbing materialPlays an important role in the formula. Advanced Institute (Shenzhen) Technology Co., Ltd. is well aware of the unique functions of various additives and uses them reasonably to improve product performance.

Dispersants can ensure uniform dispersion of absorbing fillers in the matrix resin, avoid agglomeration, and fully utilize the performance advantages of absorbing fillers. Coupling agents enhance the mechanical properties of coatings and improve their adhesion and strength by improving the interfacial bonding between absorbing fillers and matrix resins. Plasticizers can increase the flexibility of coatings and prevent cracking due to environmental changes during use. The addition of antioxidants and UV absorbers can effectively improve the aging resistance of coatings and extend their service life.

In the process of formula design, Advanced Institute (Shenzhen) Technology Co., Ltd. will precisely control the types and amounts of functional additives according to the specific requirements of the coating, in order to achieve the best comprehensive performance improvement effect.

In depth research and utilization of synergistic effects

The synergistic effect between each component is one of the key factors in optimizing the formulation of coating absorbing materials. Advanced Institute (Shenzhen) Technology Co., Ltd. has invested a large amount of resources in research to explore the interaction laws between absorbing fillers, matrix resins, and additives.

Through experiments, it has been found that certain absorbing fillers have good interfacial interactions with specific matrix resins, which can promote the propagation and loss of electromagnetic waves in coatings, thereby significantly improving the absorbing performance. Meanwhile, the reasonable combination of some additives with absorbing fillers or matrix resins can not only enhance the absorbing performance, but also improve the mechanical and weather resistance of the coating.

In order to fully utilize these synergistic effects, Advanced Institute (Shenzhen) Technology Co., Ltd. adopts advanced experimental design methods, such as orthogonal experiments, response surface experiments, etc., to systematically study the relationships between each component, find the optimal formula combination, and achieve synergistic effects between each component.

Combining advanced technology to achieve performance breakthroughs

     Advanced Institute (Shenzhen) Technology Co., LtdUnderstood, optimizing the formula is only the first step, and advanced preparation techniques are needed to truly achieve a breakthrough in the comprehensive performance of coating absorbing materials.

In the preparation process, the company adopts advanced technologies such as high-speed stirring and ultrasonic dispersion to ensure that the absorbing filler is highly uniformly dispersed in the matrix resin. By precisely controlling the stirring speed, time, and ultrasonic parameters, the dispersion quality of the filler is improved, thereby enhancing the consistency of the coating's absorption performance.

In terms of coating forming technology, Advanced Institute (Shenzhen) Technology Co., Ltd. selects suitable coating methods such as spraying, brushing, scraping, etc. according to different application needs, and strictly controls process parameters such as spraying pressure, temperature, humidity, etc. to ensure the thickness uniformity and surface quality of the coating.

In addition, the company actively explores and applies new preparation technologies, such as nanocomposite technology, multi-layer structure preparation technology, etc. Nanocomposite technology can achieve uniform composite of absorbing fillers and matrix resins at the micro level, improving the comprehensive performance of coatings. The multi-layer structure preparation technology achieves multi-level absorption and loss of electromagnetic waves by designing combinations of different functional layers, further expanding the absorption frequency band and improving absorption efficiency.

Advanced Institute (Shenzhen) Technology Co., Ltd. has made active efforts to improve the comprehensive performance of coating absorbing materials by carefully selecting and matching absorbing fillers, matrix resins, and functional additives, conducting in-depth research on the synergistic effects between each component, and combining advanced preparation processes to continuously optimize the formula of coating absorbing materials. In the future, the company will continue to uphold the spirit of innovation, constantly explore and research, and contribute more to the development of the coating absorbing material industry.
