Abstract

Method for obtaining binder compositions for manufacturing molds and casting cores, characterized in that in a first stage a starch hydrolysis product having a dextrose equivalent between 5 and 75, particularly between 10 and 40, is subjected to hydrogenation reaction to obtain a stabilized starch hydrolyzate having a dextrose equivalent of less than 5; and in a second step, the resulting starch hydrolyzate is contacted, in aqueous solution, with an alkali metal silicate.
