Abstract:
A phenolic-type phosphorous curing agent works by grafting a phosphorous compound onto a benzene ring to substitute hydrogen atoms and is halogen-free and nonflammable; when acting with and curing an epoxy resin, the curing agent helps to form a higher crosslink density and excellent heat tolerance to let the epoxy resin suitable for use in making PCB's insulating layer or semiconductor packaging as well as to endow the PCB's insulating layer or semiconductor packaging provided with excellent flame retardance and high glass transition temperature (Tg).
