Abstract

A fire resistant phenolic resole-resorcinol novolac system for a pultrusion process, having a much improved pot life of the two part mixture, lower emissions during processing and a much better surface finish of the pultruded composite when compared to a similar existing system. A method of making a phenolic resole for pultrusion including, but not limited to, the use of modified phenols such as p-phenyl phenol and nonyl phenol.
