Waterborne paint gradually occupies a share, and the market was not dominated by paint alone any more. Compared with traditional paint industry, waterborne paint has various advantages, among which, environmental protection is the most important one, and it is sure to lead the development of times in the future coating industry.
"In the future, water-based paint will gradually replace paint in China. It's a necessary process because water-based paint is both energy efficient and environmentally friendly and low cost." Jin Yong, an academician of the Chinese Academy of Engineering, said at a recent "Green Development · Ecological Economy" event jointly organized by Hebei Provincial Department of Science and Technology and the government of Baoding that China's coating industry will shift to water-based paint.
Compared with traditional paint, water-based paint is more environmentally friendly
It is understood that a water-based paint enterprise with an annual capacity of 125,000 tons can save 100,000 tons of solvent and 200,000 tons of oil every year compared with a traditional paint factory with the same capacity; save 286,000 tons of standard coal; reduce 715, 000 tons of carbon dioxide, equivalent to the emissions of 100, 000 cars a year.
In addition, according to statistics from authoritative department, domestic paint discharges 7 million tons of organic volatile to the atmosphere in use every year.
Academician of the Chinese Academy of Engineering: water-based paint tends to dominate the industry
"The damage of traditional paint lies mostly in its solvents. These organic solvents, which are basically gasoline, release large amounts of organic matter, which is a source of PM2.5 and is harmful to human health." Jin Yong said that water may evaporate during waterborne paint drying. “You can't say the process is completely free of pollution, but compared to paint, it is at least many times less, and pollution to the environment is greatly reduced”.
Paint has long been banned in many countries because of its hazards in production and use. In order to control environmental pollution and protect human health, the EU banned the production and sale of paint in EU countries as early as January 1, 2004, and changed solvent-based paint to water-based paint. The United States also restricted Chinese paint furniture from entering the market in 2004.
Inadequacy: at present, waterborne paint lags behind oily coating in hardness, plumpness, durability and other aspects, so the cost performance of oily coating is higher apparently. Accordingly, oily coating still holds dominant position on coating market, waterborne paint still cannot shake its position, and besides the low market perception, cost performance and cost of business transformation are also the main factors that hinder its development.
The above is a few conditions that water-based paint faces in coating industry. Although there are challenges, water-based paint is sure to cause a revolution in coating industry with its powerful advantages.
