Abstract
A halogen-free varnish includes epoxy resin, composite curing agent, condensed phosphate, and filler. The composite curing agent includes Benzoxazine (BZ) resin and amino triazine novolac (ATN) resin. The filler has aluminium hydroxide and silica. Glass fabric is dipped into the varnish so as to form a prepreg with better thermal stability, anti-flammability, and low moisture absorption.
