In recent years, as the national economy has grown rapidly, more people are embracing a low-carbon lifestyle. When it comes to home renovation, one of the most important aspects of life, environmental protection and performance of coatings have become key concerns for homeowners. These growing demands have laid a strong foundation for the development of water-based coatings. But what exactly are water-based paints? How have they evolved, and where might they be headed in the future?
Waterborne coatings refer to paints that use water as a solvent or dispersant, making them more environmentally friendly compared to traditional solvent-based options. Their eco-friendly nature has already won over many consumers. However, despite this, China’s current water-based coating industry still lags behind the ideal of being truly "low-carbon." There is a noticeable gap between what is marketed as "water-based" and what is actually environmentally sound.
Modern consumers are increasingly aware of health and environmental issues, and low-carbon living has become a trend. Water-based paints are seen as the closest alternative to achieving this goal. Currently, only waterborne wood coatings are showing real potential in competing with traditional products.
In 2009, China's total coating production reached 7.55 million tons, with water-based paints accounting for about 43% of the total output—around 3.21 million tons. However, when it comes to wood coatings specifically, the situation is different. In the same year, approximately 800,000 tons of wood coatings were used, but only 2% were water-based, while 98% were solvent-based.
Looking ahead, the market share of water-based coatings is expected to rise significantly. Over the next five years, it could reach 30% or even higher. This shift is partly due to rising oil prices, which have led to increased costs for oil-based paints. As a result, some water-based paints have become more competitive in price, giving them a boost in the market.
Despite these positive signs, challenges remain. Many companies are still hesitant to invest in water-based technologies due to short-term thinking. Additionally, there are gaps in policy support, technological innovation, and public awareness. Learning from the experiences of Europe and the U.S., where strict regulations helped drive the transition to water-based coatings, China needs to take similar steps to accelerate its own progress.
One of the main drawbacks of water-based wood coatings is their performance, particularly in terms of hardness, wear resistance, and film quality. While they offer environmental benefits, they still lag behind traditional paints in certain areas. However, with rising raw material costs pushing up the price of oil-based paints, water-based options are becoming more attractive.
The overall promotion of water-based coatings is still hindered by immature processes and less developed physical properties. Until these issues are resolved, water-based paints will not have a clear advantage in the market. That said, in the long run, it's likely that water-based paints will gradually replace solvent-based ones, especially in furniture and household applications.
As consumer demand for eco-friendly and healthy products continues to grow, the water-based paint industry is expanding rapidly. New innovations are emerging, and the market space for these products is widening. With the right policies, investments, and education, China's water-based paint industry is well-positioned for significant growth.
However, it's important to recognize that water-based coatings are not a perfect solution. They cannot yet fully replace solvent-based paints in all applications. Ongoing research is needed in basic materials, film-forming substances, and process optimization to make water-based coatings more competitive. As experts emphasize, the development of this industry should be based on solid foundations rather than speculation. Claims like “zero VOC†must be backed by real evidence.
There are differences in commercial glass and home glass in multiple aspects:
1. Use
Commercial glass:
-It is mainly used for commercial buildings, such as office buildings, shopping malls, hotels, etc. Its functions often need to meet the specific needs of public spaces. For example, the glass window of large shopping malls requires good display effects and attract customers' attention.
-In some commercial places, such as banks, jewelry shops, etc., glass may need higher security, such as bulletproof and anti -theft.
Home Glass:
-In for family houses, such as windows, doors, furniture, etc. Pay more attention to meeting the needs of family life, such as providing lighting, protecting privacy, and decorating home furnishings. For example, the window glass of the bedroom may choose to have a shading function to ensure sleep quality.
2. Performance requirements
Commercial glass:
-The intensity requirements are high, and can withstand greater traffic and possible external forces. For example, the glass curtain wall of a commercial building needs to withstand the test of natural factors such as wind and rain, wind pressure.
-The optical performance may require higher transparency and uniformity to ensure the brightness and beauty of the business space.
-An sound insulation performance is also very important, especially in hotels, conference rooms and other places, need to reduce interference of external noise.
Home Glass:
-A safety is the key, especially for families with children and the elderly. Safe glass such as tempered glass may be selected to prevent serious damage to people when crushing.
-The insulation performance is also important, which can effectively reduce the energy consumption of the family. For example, double -layer hollow glass can play a better thermal insulation effect.
3. Design characteristics
Commercial glass:
-In large size, to meet the needs of large -scale lighting and open vision of commercial buildings. The design pays more attention to the coordination with the overall style of the building, reflecting the sense of modernity and fashion.
-It special coating technology, such as low -radiation coating glass to reduce energy consumption and ultraviolet radiation.
Home Glass:
-The design is more diverse, and you can choose different colors, patterns and textures according to the family decoration style. For example, art glass can add an artistic atmosphere to home.
-If attention to details and humanized design, such as easy cleaning, convenient installation, etc.
