1.3 Chemical Properties<\/h3>\n

BDMA has strong alkalinity and catalytic activity, and can react with a variety of organic compounds, especially in the curing process of epoxy resins, which show excellent catalytic properties. <\/p>\n

2. Application of BDMA in electronic component packaging<\/h2>\n

2.1 Epoxy resin curing agent<\/h3>\n

BDMA, as a curing agent for epoxy resin, can significantly increase the curing speed and curing degree. Its catalytic action allows the epoxy resin to cure quickly at lower temperatures, thereby reducing production cycles and energy consumption. <\/p>\n

2.1.1 Curing mechanism<\/h4>\n

BDMA reacts with epoxy groups through nucleophilic addition reaction to generate a stable crosslinking network structure. This structure not only improves the mechanical strength of the material, but also enhances its heat and chemical resistance. <\/p>\n
