[Chemical Knowledge]：The nature, use, upstream and downstream raw materials, storage methods, water-based paint problems.

Waterborne Coatings Properties

Water-based coatings, as the name suggests, use water as the main solvent. Compared with traditional solvent-based coatings, it has many significant advantages. The environmental performance of water-based coatings is excellent, because it does not contain or contains less volatile organic compounds (VOCs), which reduces the pollution to the atmosphere and is safer for human health. Water-based coatings have good weather resistance and corrosion resistance, and can maintain stable performance under different environmental conditions. Water-based coatings dry quickly, convenient construction, reduce construction time and cost.

Water-based coatings use

Waterborne coatings are widely used in construction, automobile, furniture, electronics, electrical appliances and other fields. In the construction field, water-based coatings are used for interior and exterior wall decoration, waterproof coating, etc., because of its environmental protection and non-toxicity, it has become the first choice for home decoration. In the automotive industry, water-based coatings are used for body painting, which not only provides high-quality surface effects, but also effectively reduces environmental pollution. In furniture and wood painting, water-based coatings are often used for surface protection and decoration of wooden furniture because of their high transparency and good wear resistance. The application of water-based coatings in the fields of electronics and electrical appliances is also gradually increasing, such as the coating of mobile phone shells and home appliance shells.

Waterborne coatings upstream and downstream raw materials

The production of waterborne coatings involves a number of upstream raw materials. The main raw materials include emulsions, pigments, fillers, additives and water. Emulsion is the core component of water-based coatings, usually using acrylic emulsion, polyurethane emulsion, epoxy emulsion and so on. Pigments are used to give paint color, common titanium dioxide, iron oxide red and so on. Fillers such as calcium carbonate, talc, etc., are used to increase the volume of the coating and improve the performance of the coating film. Additives include dispersants, leveling agents, preservatives, etc., to improve the performance of the coating. Water acts as a solvent to adjust viscosity and fluidity.

The downstream market is mainly a variety of coating enterprises and consumers. Construction companies, car manufacturers, furniture manufacturers, etc. are the main users of water-based coatings. These downstream enterprises have higher requirements for the environmental performance, construction convenience and durability of coatings, which promote the continuous development and innovation of water-based coating technology.

Water-based paint storage method

The storage method of waterborne coatings directly affects their quality and performance. Water-based coatings should be stored in a dry, cool, ventilated place, avoid direct sunlight and high temperature environment. Excessive temperature will cause the water in the coating to evaporate, affecting the fluidity and workability of the coating. The storage container must be well sealed to prevent moisture and oxygen in the air from entering, causing deterioration and mildew of the paint. For the paint that has been opened, it should be used as soon as possible, and the unused part should be resealed, and the opening date should be marked. The storage environment of water-based coatings should be far away from fire and heat sources to prevent fire hazards.

WATER-BORNE COATINGS MARKET TREND AND DEVELOPMENT

With the increasing awareness of environmental protection and the increasingly stringent regulations, the water-based coatings market is showing a rapid growth trend. Government restrictions on VOCs emissions have driven the popularity of water-based coatings. Consumer demand for health and environmental protection products has also promoted the widespread application of water-based coatings. Technological innovation makes waterborne coatings gradually catch up with traditional solvent-based coatings in performance, such as wear resistance, corrosion resistance and decorative effect have made significant progress. In the future, with the application of nanotechnology and functional materials, the performance and application of water-based coatings will be further expanded.

Waterborne Coatings Challenges and Future Directions

Although waterborne coatings have many advantages, they still face challenges in certain application areas. For example, under extreme weather conditions, they may not be as durable as solvent-based coatings. In some industrial fields with high performance requirements, such as aerospace and marine coating, the application of water-based coatings needs to be further optimized and improved. In the future, the development direction of water-based coatings includes improving the comprehensive performance of coatings, reducing production costs, and developing new environmentally friendly raw materials. Strengthening the research of coating application technology and providing more professional construction solutions are also important ways to enhance the market competitiveness of water-based coatings.

Conclusion

Water-based coatings are becoming an important part of the coatings market due to their environmental, health and safety characteristics. Through continuous technological innovation and market expansion, water-based coatings will play their advantages in more fields. Although there are still some challenges, with the advancement of industry technology and the growth of market demand, the development prospects of water-based coatings are very broad. In the future, how to improve the performance and application of water-based coatings will be the focus of the industry.
