Mar 15, 2016There are four different types of acid (medium, weak and very weak): the choice of an acid is essentially conditioned by the sand temperature (in summer a weak acid is preferable, in winter a stronger one), but also by the type of sand, of resin and by the required hardening speed. The fundamental properties of these acids are reported in table 4.
