According to a report in the financial sector on May 24, 2025, information from the National Intellectual Property Administration shows that Shanghai Jeatan  New Materials Technology Co., Ltd. has applied for a patent titled "An epoxy curing agent and its preparation method", publication number CN120025549A, and the application date is April 2025.

The patent abstract shows that the present application relates to the field of epoxy curing agents, and specifically discloses a kind of epoxy curing agent and its preparation method. The epoxy curing agent is a polymer compound obtained by reaction other than carbon-carbon unsaturated bonds, and the reaction process specifically includes: isophorone diamine, triisocyanate triglycidyl ester and dimer acid diglycidyl ester are reacted to obtain product I; phenols, product I and aldehydes are mixed under the protection of inert gas and then post-processed to obtain product II; product I and product II are mixed to obtain a mixture; the mixture and epoxymethoxysilane are reacted, and aminosilane is added to mix evenly. The epoxy resin curing agent of the present application can make epoxy resin cured material have both good flexibility and high strength and heat resistance, and can be widely used in heat-generating products such as fire retardant coatings, electronic appliances, etc., and is particularly suitable for the preparation of materials such as expanded epoxy fire retardant coatings and high temperature resistant coatings.
