Investigation of Composite Materials based on Modified Novolac Phenol-Formaldehyde Resin

Abstract

It was determined that novolac phenol-formaldehyde resin modification by polyvinylpyrrolidone and epoxy-dianic resin results in a significant improvement of thixotropic characteristics and enamel technological effectiveness and in physico-mechanical properties and thermostability improvement as well. The developed modified composition is characterized by high index of thixotropy in contrast to phenol-formaldehyde resin containing urotropine.
