Dymax Electronics Adhesives and Coatings Meet New China Low VOC Standards

Dymax Products Help Consumer Electronics and Automotive MFC


Respond to China New VOCs Standards for Coating and Adhesives

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. 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 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 to environment 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.

Manufacturers normally pay attention to the following two questions: 

1. Dymax adhesives and coatings are produced abroad then imported to China. Do they need to meet the new national standards when sold to China or used in production in China?

Answer: Yes. 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.

2. Can Dymax provide VOCs certificates for adhesives and coatings?

 Answer: Yes. 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.

Dymax戴马斯产品助力消费电子和汽车制造商应对VOCs管控新国标

2020年国家市场监督管理总局(SAMR)、国家标准化管理委员会(SAC)陆续发布了9项涉及挥发性有机物(VOCs)的国家强制标准,规范了涂料、胶粘剂、油墨和清洗剂中VOCs测试方法及含量限值,部分新标准将会代替旧版标准。例如,消费电子制造业中常用到的胶粘剂需满足《GB 33372-2020胶粘剂挥发性有机化合物限量》的标准。电子和汽车制造行业中常用到的三防漆和涂料的使用则需满足《GB 30981-2020工业防护涂料中有害物质限量》的标准。

UV胶配方中不含非活性稀释剂,辐照或加热时,几乎所有成分都参与固化反应,使得UV胶在固化后VOC含量极低,不会造成环境污染且对人体无害。UV胶顺应社会环保趋势发展,是绿色型胶粘剂。新国标的发布引起相关行业制造企业的高度重视,作为UV胶领先生产商的Dymax戴马斯也在积极助力制造商应对VOCs管控新国标,规避环保违规风险。

制造商常关注的问题主要有以下两个:

一、Dymax戴马斯的胶粘剂和涂料等产品目前在国外生产,在中国销售或使用时是否需要满足新国标相关要求? 答:需要。国家生态环境部要求严格落实国家和地方产品VOCs含量限值标准,标准生效后,生产、销售和使用胶粘剂、三防漆和涂料均应满足新颁布实施的国家产品有害物质限量标准要求,所以,国外生产的这些产品进口至国内销售或生产使用时,需要满足GB 33372-2020和GB 30981-2020的相关要求。

 二、Dymax戴马斯可以提供胶粘剂和涂层等产品的VOCs证明吗? 答:可以。Dymax戴马斯可按需提供经内部测试的产品VOCs含量申明文件,证明产品所属类别符合在其应用领域的的相关新国标规定。部分电子组装应用中的产品已通过第三方测试认证机构SGS的新国标
