做环氧固化体系产品的都知道：冬季低温固化慢、薄层涂覆不干、修补工序效率低，一直是生产与施工中的老大难问题。传统胺类固化剂冬季固化非常慢，这不仅增加生产成本，还拉长作业周期，严重制约产能与现场施工效率。
Addressing core pain points in the epoxy adhesive industry, Guangzhou Feisi's thiol series curing agents are the ideal partner for epoxy systems. Leveraging highly active intramolecular thiol groups, they efficiently catalyze ring-opening crosslinking of epoxy resins, enabling rapid curing at room or low temperatures with stable formation even in thin layers. This makes them the preferred curing system for craft adhesives, electronic insulation adhesives, structural construction adhesives, repair adhesives, and composite material adhesives.
