ABSTRACT:
A varnish includes resin and composite curing agent. The composite curing agent includes curing agent of polyphenylene methylphosphonate resin and curing agent of phenol resin. Glass fabric cloth is dipped into the varnish so as to form a prepreg with better thermal stability, anti-flammability, and low absorbent ability. Furthermore, the composite curing agent can be provided for higher curing rate.
