summary of relevant national and industrial standards for waterborne industrial coatings

february 23, 2021

in recent years, water-based industrial paint has become a hot term in the industry. With the gradual emergence of the concept of environmental protection in the terminal market, consumers' awareness of environmental protection is also increasing at low prices, gradually moving closer to environmentally friendly coatings. In the case of large-scale control over the production and coating of oil-based coatings in the industrial field, the "oil to water" policy has been promoted, and the fields of electromechanical equipment, auto parts, hardware accessories, etc. gradually tend to water-based industrial coatings

the following is a brief summary of the current national and relevant industry standards:

01 the latest standard

in the new national standard gb24409--2020 limits of harmful substances in vehicle coatings, which has been implemented since December 1, 2020, the limited value of VOC content of water-based coatings and radiation curing coatings and the control project of total content of benzene series of water-based coatings and water-based radiation curing coatings have been added. This is the application of water-based coatings in the field of vehicles. It gives a clear reference standard for the limit value of VOC content, and also puts forward a mandatory standard for the production and application of vehicle water-based coatings

in the new national standard gb30981--2020 industrial protection B. test article data: provide users with the set limit of harmful substances in coatings, which has been implemented since December 1, 2020, the limit value of VOC content of water-based coatings, solvent-free coatings and radiation curing coatings has also been added. This is a clear reference standard for the limit value of VOC content of waterborne coatings in industrial applications
