In today's era of increasingly stringent environmental regulations, the coatings industry is undergoing a profound green transformation. Balancing the outstanding performance of oil-based coatings with the environmental advantages of water-based coatings is not a simple "either-or" choice; rather, it is achieved through technological upgrades, scene segmentation, and policy guidance, enabling the harmonious coexistence and complementarity of the two.
Firstly, water-based coatings are the dominant force in the indoor and residential sectors. Due to their water-based dilution characteristics, water-based paints have extremely low VOC (volatile organic compounds) content (typically < 50g/L), are non-toxic and odorless, and do not require long-term ventilation after application, significantly reducing health risks. Since 2025, new regulations have clearly restricted the use of solvent-based coatings in interior decoration, schools, hospitals, and other places. For household furniture, children's rooms, and general building exteriors, water-based paints have become the preferred solution due to their excellent environmental performance and increasingly improved wear resistance and weather resistance.
Secondly, oil-based coatings have not disappeared but are transforming towards "high solids low viscosity" and "special applications". In highly demanding fields such as heavy corrosion protection, ships, and industrial facilities in extreme climates, traditional oil-based coatings still have irreplaceable advantages. To balance environmental protection, modern oil-based coatings are significantly reducing solvent usage, increasing solid content (high solid content coatings), or using active diluents instead of traditional organic solvents, thereby significantly reducing VOC emissions. Additionally, strict construction enclosure management and efficient waste gas recovery systems are also key means for oil-based coatings to achieve environmental compliance in industrial scenarios.
Finally, powder coatings and UV-curable coatings, as the "zero VOC" third pole, are filling the gap between the two. They are completely solvent-free, solving the pollution problem at the source, and are widely used in household appliances, automotive components, and other fields.
In conclusion, the strategy of balancing environmental advantages is: full water-basedization in residential interiors, low-carbon oil-based coating in high-end industrial fields, and promotion of solvent-free in emerging fields. This diversified technical route not only meets the performance requirements of different scenarios but also jointly promotes the green and sustainable development of the coatings industry.
