I. Basis Of Coating Technology
Coating technology is a comprehensive technology involving several disciplines. It is based on chemistry and covers a wide range of knowledge such as organic chemistry and physical chemistry. In the process of coating preparation, it is crucial to understand the chemical reaction mechanism between various raw materials, such as the synthesis of resin, cross-linking reaction between curing agent and resin. At the same time, physical chemistry also plays an important role in the rheological properties of coatings, surface tension, etc. Therefore, coatings technology has its own complexity and multiplicity, which is worthy of careful study and deep plowing.

II. Current Mainstream New Coating Technologies

1. Water-based coating technology:

Water-based coatings have developed rapidly in recent years, it uses water as the dispersion medium, replacing the traditional organic solvents, the biggest advantage brought about by this change is its environmental friendliness. Water-based coatings in the production and use of the process greatly reduces the volatile organic compounds (VOC) emissions, for the benefit of the environment has made a great contribution.However, at the same time, waterborne coatings also face some technical challenges, such as the speed of drying, the humidity and temperature requirements of the construction environment. In order to overcome these problems, our R&D personnel are studying new water-based emulsion systems, efficient drying agents and other technical means, in anticipation of more cost-effective products that will continue to improve the quality of life in human society.

2. Powder coating technology

Powder coating is a solvent-free, 100% solid powder coating. It is characterized by significant environmental advantages, no organic solvent volatilization in use.The coating process of powder coating is relatively complex and requires specialized equipment, such as electrostatic spraying equipment. Moreover, during the storage and transportation of powder, it is necessary to prevent the powder from moisture caking and other problems. At present, to improve the coating efficiency of powder coatings, improve the quality of the coating, such as improving the flatness of the coating and adhesion, etc. is the focus of this type of coatings need to research breakthroughs.

3. High-solid coating technology

High-solid coatings have high resin content and low organic solvent content, which can reduce VOC emission while ensuring coating performance. Through the improvement of polymer structure and formulation design, improve the efficiency of active diluents and other means to continuously improve the solid content of coatings to meet the environmental requirements and performance needs.

Ⅲ.Emerging Coating Technologies
1. Self-healing coating technology
This is a very innovative coating technology. When the coating is slightly damaged, such as scratches, self-healing coatings can automatically repair the damaged area. The principles include the release of repair agents from microcapsules or the use of self-healing properties of polymer materials. This kind of coating has potential huge application value in high-end automobile, electronic products and other fields.
2. Smart Coating Technology
Smart coatings break the limitations of traditional coatings with a single function. For example, temperature-sensitive smart coatings that change color or physical properties with changes in temperature. Another is smart coatings with antibacterial function, which can automatically release antibacterial substances by sensing the number of bacteria in the environment.

IV. Challenges and Opportunities For Coating Technology

1. Challenges
Higher environmental protection requirements: With the continuous strengthening of global environmental protection awareness and regulations, coating technology needs to develop in a more environmentally friendly direction. New environmental protection standards are becoming more and more stringent on VOC emissions, harmful substances content, etc., which requires coatings technology to be continuously innovated.
Synergistic multiple performance: the user’s requirements for coating performance are becoming more and more diversified, in order to ensure environmental protection at the same time, but also need to have, such as good corrosion resistance, abrasion resistance, weathering and other properties, which puts forward higher requirements for the formulation design and manufacturing process of the coatings.
Cost control: The development and application of new technologies are often accompanied by cost increases. In an increasingly competitive market, how to improve coating technology while controlling costs is an important challenge for coating enterprises.
2.Opportunities
Demand from emerging industries: With the rapid development of new energy vehicles, 5G communications, aerospace and other emerging industries, the demand for coatings is also growing. These industries have different performance requirements for coatings, providing a broad market space for the innovation of coating technology.
Consumption upgrading: Under the trend of consumption upgrading, consumers are willing to pay for high-quality, high-performance and multi-functional coating products. This prompts coating enterprises to increase investment in technology research and development, which helps to promote the development of coating technology.
