Generally, the binder used in hammered sand for hooks is a resin obtained by reacting phenol and formaldehyde in a hostile or alkaline environment.
When it is used in sand molds for deliveries where the casting temperature is low, such as the phenol Ij resin aluminum castings of et al., a very large amount of cost and labor is required to remove the sand after casting.

According to
Accelerates the dehydration reaction of polymers containing R and promotes carbonization.
It is believed that the flame retardancy is improved due to the ashing effect. It is thought that the disintegrability of the phenol UIJ11 decreased because the cohesive force of the sand grains decreased.
