Low-quality curing agent seriously restricts the quality improvement of unsaturated products. In many cases, the unqualified products are not caused by resin, but caused by the use of unqualified curing agent. At present, there is still a certain gap between the quality of domestic curing agent and the international one. Therefore, the industry needs to work together to improve the technological level and supply capacity. The revision of this standard means to improve the quality index of methyl ethyl ketone peroxide curing agent and actively integrate with international standards.

On July 9, the first working meeting of the group standard "Standard for Styrene Volatile Limit of Low Styrene Volatile Unsaturated Polyester Resin" was held in Jiujiang. As a group standard drafter, Fangxin Resin actively participated in this working meeting, and has been working hard to promote the research and development and promotion of environmentally friendly resins!

With the implementation of the newly revised "Environmental Protection Law" and the improvement of the overall environmental protection level of the industry, the main source of VOCs in the production environment of unsaturated resin-based composite materials is styrene, and reducing the volatilization of styrene is the most direct and effective method. Therefore, the industry urgently needs to have a definition for low styrene volatile resin, and a detection method and standard for the volatile limit value.

"Styrene volatilization limit standard of unsaturated polyester resin with low styrene volatilization" specifies the terms and definitions, requirements, test methods, limit value (relative value, absolute value) of styrene volatilization of unsaturated polyester resin with low styrene volatilization value) and other requirements. The standard applies to unsaturated polyester resins (including vinyl ester resins). The formulation of this standard can guide the production and application units of unsaturated polyester resins to choose low styrene volatilization unsaturated polyester resins, reduce VOCs emissions during the use of resins, reduce losses, and protect the environment.

For more than 20 years, Fangxin Resin has always stood with the industry, taking the industry as a benchmark, strengthening foreign exchanges, actively participating in industry conferences, drafting and formulating industry-related norms and standards, and demanding itself with high requirements and high standards, and constantly improving The ability of independent innovation and process optimization of the enterprise contributes to the sustainable development of the composite material industry and makes progress together with the industry!
