The content limit of some types of VOCs has been further tightened according to the technical development of the industry and the actual situation of Beijing.
Controlling VOCs and controlling volatile organic compounds (VOCs) emission is the key to the coordinated control of fine particulate matter (PM2.5) and ozone (O3).
At the same time, the limit value of adhesives for indoor decoration is stricter than that for similar outdoor buildings.
The content limit has been tightened.
Generally speaking, the limit level of architectural coatings is stricter than the national mandatory standard, which is equivalent to the national recommended standard for coatings with low VOCs content, and continues the leading position of the original standard in China; In building adhesives, the limit level of solvent type is stricter than the national standard, and the use of water-based and native adhesives with low VOCs content is guided.
In accordance with the principles of convergence with national standards, industry-leading, feasible technology and market availability, Beijing revised the original standards to further reduce VOCs emissions from architectural coatings and adhesives.
❖ on April 1, 2022, Beijing revised and issued a new version of the standard for the content limit of volatile organic compounds in architectural coatings and adhesives (DB11 / 1983-2022) (hereinafter referred to as the new standard), which will be implemented from October 1 this year.
With the technological progress of the industry, products with low VOCs content are more common.
The product classification method of the new standard has been adjusted according to the latest requirements of the national standard, and product types such as fire retardant coating and decorative board coating have been added, with a total of 39 indicators in 8 categories.

In recent years, the state has successively issued a number of new standards for architectural coatings and adhesives, further tightening the VOCs content limit requirements.
In order to implement the regulations of Beijing Municipality on the prevention and control of air pollution and reduce the emission of VOCs during the use of building coatings and adhesives, in 2017, our city issued the first VOCs product standard, the standard for the content limit of volatile organic compounds in building coatings and adhesives (DB11 / 3005-2017) (hereinafter referred to as the original standard), which controls the whole process of the production, sales and use of building coatings and adhesives, Effectively promote the source emission reduction of VOCs in the field of building decoration.
The VOCs content level is usually only tens of grams / L, which is 1 / 5 or lower of similar solvent products, and has relatively little impact on the environment and health.
Architectural coatings and adhesives are one of the important sources of VOCs.
After the implementation of the new standard, Beijing market supervision, housing and urban rural construction and other departments will, in accordance with the requirements of laws and regulations, strengthen the sampling supervision of relevant products in all links of the city’s enterprise production, supermarket market and online sales, construction and use, and promote the effective implementation of the standard.
In order to facilitate consumers to quickly understand the VOCs content information of products, the simplification and optimization are carried out on the basis of continuing the requirements of the original standard, highlighting the product type, VOCs content value and other key information.
The original standard product packaging marking system has been optimized.
The green initiative selects low VOCs content products, water-based and other non solvent products.
It is suggested that citizens and friends should give priority to non solvent products with low VOCs content on the premise of meeting the use functions and jointly practice green life.
Therefore, it is suggested that when purchasing architectural coatings and adhesives, all units should carefully check the packaging marks to ensure that the purchased products meet the requirements of the new standards.
For the products produced and sold in this city, in addition to the original product description, the product type, classification, purpose, VOCs content value and construction proportion under construction state need to be supplemented on the minimum sales packaging marking.
The main changes of the new standard are as follows: the classification method has been adjusted.
