Abstract

Изобретения относится к композициям и способам для уменьшения запаха и выделения формальдегида во время производства и отверждения форм и стержней, особенно таких стержней и форм в литейной промышленности, которые содержат отверждаемые сложным эфиром фенольные связующие. Более конкретно, в данном случае в состав включен сложноэфирный отвердитель, содержащий сложный эфир и резорцин, который, когда он представлен в композиции со смолой и заполнителем, эффективно поглощает формальдегид, в результате чего снижает выделение и запах формальдегида из композиции.
