Abstract
Método para preparar artículos compuestos tales como, por ejemplo, moldes de arena para fundición en el que se da a un material sólido, tal como fibra de vidrio o arena, la forma de un artículo sólido con resina como adhesivo, que comprende las etapas de : formar un adhesivo mezclando una resina resol-fenólica líquida y una resina de furano-formaldehido líquida producida por condensación ácida de furano-formaldehido, bajo condiciones en las que se mantiene un exceso de furano, mezclar dicho adhesivo con un material sólido catalizado con ácido, siendo usado dicho adhesivo en cantidades entre 0,5 y 4 por ciento en peso, dar forma a la mezcla resultante de adhesivo-material sólido catalizado, y permitir que la resultante masa con forma permanezca en dicha forma durante un periodo de tiempo suficiente para que el adhesivo endurezca.
