Abstract

LA RESINA SE PREPARA MEDIANTE LA REACCION DE UN FENOL, UN ALDEHIDO Y UN COMPUESTO DE HIDROXIDO ALIFATICO QUE CONTIENE DOS O MAS GRUPOS HIDROXIDOS POR MOLECULA EN LA PRESENCIA DE UN CATALIZADOR DE IONES DE METAL DIVALENTE. ESTAS RESINAS REACCIONAN CON POLIISOCIANATOS PARA FORMAR POLIURETANOS QUE SON UTILES COMO AMALGAMADORES PARA NUCLEOS Y MOLDES DE FUNDICION.
