International paint industry presents three major development directions

With the rapid growth of the global paint industry, new technologies and innovative products continue to emerge, intensifying market competition. The international architectural coatings sector is currently witnessing three major development trends. Firstly, the shift toward waterborne coatings is accelerating. As the world moves toward reducing volatile organic compounds (VOCs), water-based paints have become a key direction in the industry. Traditional solvent-based paints are gradually losing ground, while waterborne coatings are gaining momentum. However, low-grade polyvinyl alcohols still dominate the market. Improving the quality and developing advanced waterborne coatings are crucial for their long-term success. Research should focus on vinyl acetate-acrylic copolymer emulsions, styrene-acrylic copolymer emulsions, and pure acrylic latex paints, aiming for enhanced durability, smoothness, fullness, and ease of application. For more mature systems like epoxy emulsions and waterborne polyurethanes, further research into high-performance aqueous coatings is needed to meet specific industrial demands. Secondly, functional coatings are evolving beyond basic features such as fire resistance, anti-virus properties, and thermal insulation. There's a growing need to address complex challenges in architectural decoration through advanced compounding technologies that can enhance multiple functions simultaneously. Thirdly, combining functionalities is becoming a key strategy. For example, integrating elasticity with breathability by using elastic emulsions and hydrophilic-modified microshells allows both flexibility and moisture permeability. Similarly, combining elasticity with low-pollution properties using room-temperature reaction-type emulsions and cross-linked latex improves elongation and film density, resulting in better performance and lower staining. Research on acid rain-resistant coatings is also gaining importance, as acid rain poses an increasing threat to building materials. Developing effective base compound technologies and additives will be essential in addressing this issue. In addition to protection and aesthetics, ideal coatings should offer unique properties. New base materials, such as fluororesin coatings, have already shown excellent weather resistance and high value-added performance in construction projects. Developing water-based fluorocarbon resins, especially fluoropolymer-modified copolymers, is a promising area. These materials offer high performance at a reasonable cost, laying the foundation for next-generation high-grade coatings. Waterborne polyurethane coatings are also being prioritized due to their superior properties. Making them water-based not only reduces environmental impact but also preserves their inherent advantages. Lastly, silicone-modified acrylic coatings are gaining attention for their excellent weatherability, stain resistance, and chemical stability. Their non-toxic nature makes them a safe and viable option. Meanwhile, powder coatings are also emerging as a strong contender in the high-end architectural coatings market.
