Analysis of the current situation and problems faced by developing water-based coating
There’s a dramatic discussion about “use water based and give up solvent based”in paint industry in these two years.It is knows that the current Ministry of Environmental Protection, State Administration of Taxation and Ministry of Finance are discussing to increase the consumption tax for some solvent based coating.They may give 2-3years for paint company to adjust before the introduction of the policy. Whether it is from the environmental side or from the process of development of the industry point of view, the development of water-based paints are the trend.
Water-based coating use water as a diluent, without solvent, no benzene, toluene, xylene, formaldehyde, free TDI toxic heavy metals, no toxic effects of odor and no harmful to humans, do not pollute the environment, paint film full, bright and translucent, good flexibility as well as water-resistant, wear-resistant, anti-aging, anti-yellowing, fast drying, application convenience and other features. It can be applied on wood, metal, plastic, glass, building materials and other appearance. The solvent based paint is the paint that made from organic solvents,containing volatile organic compounds (VOC), in addition to toxic to the human body, pollute the environment, but also the explosive; Some species also contain a lot of formaldehyde, benzene,lead and other toxic substances,it is “invisible killer” for polluting the environment and harm the health of consumers. In addition, as the solvent based coating itself constitute , it lead to stringent transport conditions.
In recent years, the climate haze has repeatedly invasion of North China, South China and East China, constantly adding PM2.5 and atmospheric volatile organic compounds (VOC) emissions become the most caring problem. In this case, water-based paint becomes more and more attention for its energy-saving、environmental protection, health and safety.Many solvent-based companies also joined the ranks of the water-based coating. Eco-friendly water-based coating has significant advantage,why can not immediately replace solvent based paint in the market?
Some consumers always believe that the surface painted by solvent based coating is lubrication flat than painted by water based paint. In fact, this is related to paint services, means the technical level. A Guangzhou home decorating company responsible person said paint is "seven bottom,three surface", lacquer filled with brown eyes can use water-based transparent putty. The effect of the paint want to achieve is flat lubrication,and water-based paint can entirely achieve this effect. "The use of solvent based paint now at least several years or to more than two decades, while the use of water-based paint, mostly for the first time," he said, "If a painter can be fully in accordance with the construction of water-based paint technology, such as strict share of the water, the role can also do it. "In addition, the current price of water based paint is higher than the solvent based pcoating,that’s also a problem. However, industry insiders think that although the price of water based paint is higher than traditional solvent based paint,it guarantee the safety and environmental protection, and its brushing technique is also simple, and does not demand any additional commodities, in fact,after calculating,it will not be much higher than traditional solvent based paint.
Now, in the home building industry, "low-carbon green" concept has gradually become household name among consumers, "buy safe and heathy" consumer attitudes is now very popular. In accordance with current consumer attitudes,safe and healty is in the top, compare with solvent base paint,water based paint has this advantage in this respect, therefore, consumers, especially for family consumers can bear the price, just need to increase the awareness of the mall. Although there are encouragement from the nation and local government, water based paint company also hope the arrival of the era of water based, but that does not mean that solvent based paint will exit the stage of history quickly. State Council Development Seminar Center researcher Sun Yang said: "water-based paint is environmentally riendly,it is a green industry and it is the direction of the future development,water based paint will instead of solvent based paint in the future.
