The new "Hazardous Materials Limits for Interior Decoration Materials for Interior Wall Coatings" (GB 18582-2008) will be formally implemented as a national mandatory standard on October 1 this year. After the new standard is issued, it will be applied to paint products currently on the market. A round of survival of the fittest.
It is reported that the new standard imposes more stringent restrictions on the content of harmful substances in water-soluble interior wall coatings. The following changes have been made in the forthcoming implementation of the national standard: 1. Water-based wall putty has been added, and a limit value for hazardous substances has been specified for it; 2. A total control project for benzene, toluene ethylbenzene and xylene has been added. The total content is less than or equal to 300 mg/kg; 3. The limit value of volatile organic compounds is greatly reduced, which stipulates that the content of water-based wall coating VOC is ≤ 120 g/L, and the content of water-based wall putty VOC is ≤ 15 g/kg. VOC is the sum of volatile organic compounds that are harmful to the human body. Formaldehyde is a highly toxic substance. Formaldehyde has been identified by the World Health Organization as a carcinogenic and teratogenic substance. Due to the high VOC content of solvent-based wall coatings, China will no longer approve new solvent-based paint manufacturers since 2005.
China's paint industry is currently implementing the national standard is the "Quality Limits for Interior Decoration Materials and Interior Wall Paints" promulgated by the General Administration of Quality Supervision, Inspection and Quarantine in December 2001. The old standard stipulates that interior walls painted with VOCs (Volatile Organic Compounds) ≤ 200 g/L, that is to say, as an important indicator for determining indoor air pollution, VOC content of not more than 200 g per liter of coating is in accordance with the national Qualified standards, but European and American standards are far more stringent.
