PT Journal AU Krasinskyi, V Suberlyak, O TI Investigation of Composite Materials based on Modified Novolac Phenol-Formaldehyde Resin SO Acta Mechanica Slovaca PY 2019 BP 18 EP 22 VL 22 IS 4 DI 10.21496/ams.2018.030 DE novolac phenol-formaldehyde resin; polyvinylpyrrolidone; epoxy-dianic resin; modification; physico-mechanical properties; thixotropic characteristics; adhesion strength. AB 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. ER
