Dymax's electronics adhesives meet China’s new low-VOC standards to help consumer electronics and automotive MFC.
In 2020, the State Administration for Market Regulation (SAMR) and the National Standardization Administration (SAC) released 9 mandatory national standards relating to volatile organic compounds (VOCs), regulating the testing methods and content limits for coatings, adhesives, inks, and cleaning agents.
Regulating Testing Methods
Some of the new standards will replace the existing standards. For example, adhesives commonly used in the consumer electronics manufacturing industry shall meet the requirements of "GB 33372-2020 Limit of volatile organic compounds content in adhesive".
Conformal coatings and coatings commonly used in the electronics and automotive manufacturing industries shall meet the standards of "GB 30981-2020 Limit of harmful substances of industrial protective coatings".
UV-curable adhesives do not contain non-reactive diluents. Almost all components are involved in the curing reaction during the light or heat-curing process. As a result, they generate very low VOCs emissions and do not pose environmental hazards and health hazards for human beings. UV adhesives are more environmentally friendly and play an important role in environmentally sustainable development.
The implementation of new standards draws attention to the fact that the standards will have a significant impact on manufacturers using related products. As a leading UV adhesive manufacturer, Dymax strives to assist manufacturers in responding to the new national standard for VOCs control and preventing environmental violations.
Strict Implementation of VOCs Content Limit Standards
The Ministry of Ecology and Environment requires strict implementation of national and local product VOCs content limit standards. Adhesives, conformal coatings, and coating products produced, imported, sold, and used that contain volatile organic compounds shall meet the new standards of GB 33372-2020 and GB 30981-2020.
Dymax can provide VOCs content declaration letters of internally tested products per customer’s requests, proving that the VOCs content in a specific Dymax product does not exceed the VOCs limitation per the related new national standard.
Some products in electronic assembly applications have passed the new national standard VOCs test implemented by SGS and obtained reports to ensure that the products meet the requirements of the national mandatory standards for VOCs. In addition to the letters, the Dymax Application engineering team can provide samples to designated third-party testing agencies per the request of a customer.
The implementation date of the new national standards GB 33372-2020 and GB 30981-2020 is December 1, 2020. Dymax actively responds to the national action plan to help enterprises strengthen VOCs control and contribute to China’s Blue-Sky War.
