At present, China is still the world's largest coatings market, China's coatings continue to serve as an important engine of the world's coatings, is expected to the next three years, global coatings production and output value of the compound annual growth rate will reach 3.1% and 5.8%. 2024 January-April coatings industry to achieve the “open door red”. With the good news of the paint industry “opening red” in the first four months of 2024, the key role of high-quality sodium feldspar powder in coatings has once again become the focus of industry attention.

Sodium feldspar powder as an important industrial additives, in the coatings industry plays an irreplaceable role. Its high hardness, low electrical conductivity, good chemical stability and weathering resistance significantly improves the hardness, abrasion resistance, water resistance and stain resistance of the coating. The specialized role of sodium feldspar in the coating industry is reflected in the following aspects:

Rheological property regulation
Sodium feldspar powder, due to its unique adsorption and dispersion properties, can significantly regulate the rheological properties of coatings, including improving the viscosity, fluidity, and leveling of coatings, making coatings easier to handle during the coating process, reducing dripping and splashing, and improving coating efficiency and quality. In addition, the addition of sodium feldspar powder can also make the coating have better wettability to ensure that the coating can evenly cover the surface of the substrate and improve the coating effect.

Filling, thickening, enhancing adhesion
As a low-cost filler, sodium feldspar powder can effectively fill the voids in the paint, increase the volume and consistency of the paint, thus improving the covering power and adhesion of the paint. Its fine particle characteristics make sodium feldspar powder in the coating system can be tightly stacked to reduce the pores in the coating film, improve the denseness and durability of the coating. At the same time, the addition of sodium feldspar powder can also enhance the bonding force between the coating and the surface of the coating material, preventing the coating from peeling and flaking.

Improvement of temperature and weather resistance
Sodium feldspar powder has excellent chemical stability and thermal stability, and can still maintain the stability and performance of the coating film in high temperature and harsh environments. Its high melting point and high thermal conductivity enable the coating to resist high-temperature deformation and scorching, while also resisting the erosion of ultraviolet rays, rain, weathering and chemicals to extend the service life of the coating. Therefore, the application of sodium feldspar powder in coatings can significantly improve the temperature and weathering resistance of the coating film and meet the needs of various extreme conditions.

Improvement of mechanical strength and durability
The addition of sodium feldspar powder can enhance the mechanical strength of the coating film, including hardness, abrasion resistance and impact resistance. Its high hardness enables the coating to resist scratches and abrasion, keeping the surface smooth and beautiful. At the same time, sodium feldspar powder can also improve the anti-chalking and anti-aging properties of the coating film, preventing the coating from chalking, cracking, and flaking during use, and enhancing the durability and service life of the coating.

In the future, with the continuous growth of the global coatings market and the continuous upgrading of China's coatings industry, high-quality sodium feldspar powder will play a more critical role in the coatings industry. We have reason to believe that with the help of sodium feldspar powder and other high-quality fillers, China's coatings industry will continue to serve as an important engine for the world's coatings, and drive the global coatings industry in the direction of more environmentally friendly, efficient, and high-quality development.
