Therefore, some small coating manufacturers can make VOC very low, but the quality can not be guaranteed.When consumers purchase coatings, they can ask to see the test report of the product.

With the growing awareness of environmental protection, the requirements for environmental protection performance of coating products are also higher and higher. It is understood that in order to interpret the concept of environmental protection, manufacturers compete to drink paint and cook with paint, which is amazing. Zero VOC, nano paint, diatom mud, seaweed mud paint and other new concepts emerge in an endless stream. However, according to industry insiders, the hype of the concept of green environmental protection coating has made many coating enterprises in a dilemma of being "kidnapped" by environmental protection.

How is the environmental protection prevailing in the coating industry? It can be traced back to around 2010. At that time, led by Libang's "Jingwei 120" 5 in 1 interior wall latex paint and duluxi's bamboo charcoal fresh wall paint, the paint market began to blow a whirlwind of Jingwei. These two foreign-funded enterprises, through extensive advertising, make the concept of Jingwei become the first focus of consumers when they purchase coatings.

At present, limited by technical problems and other factors, there is almost no really zero VOC environmental protection coating on the market. Taking latex paint as an example, film-forming additives and antifreeze additives are the main sources of VOC in coatings. Some coatings can reduce VOC by reducing their dosage, but their performance will be reduced. But if we pursue the low environmental protection index blindly, after the coating is produced, it is likely to have the situation of powder falling, foaming, cracking and low scrubbing resistance.

In the coating production, environmental protection, performance and price are a comprehensive consideration process. Moreover, due to the different formulas, processes and raw materials produced by various enterprises, it is unrealistic to achieve perfection in terms of cost. This requires a balance between environmental protection, performance and price. When consumers purchase coatings, they don't need to focus on the environmental protection and VOC content. As long as they are qualified products that meet the national standards, they can purchase them at ease. "If we do not consider the quality of the coating, it is very simple to simply reduce the VOC content, just add more water. Therefore, some small coating manufacturers can make VOC very low, but the quality can not be guaranteed.

When consumers purchase coatings, they can ask to see the test report of the product. According to the introduction, the test report is the identification of each qualified coating product. The report has the seal of the testing institution, and the qualified testing institution is the national building materials testing center, the local quality and technical supervision department and the testing institution granted the legal qualification. Generally speaking, sampling inspection is more reliable than entrusted inspection. In addition, the validity period of the test report is usually two years, so consumers should see the time clearly and be careful not to be hoodwinked by the overdue test report.
