Hands on advice for successful sand reclamation

Phenolic-urethane resin systems are diluted (extended) with a solvent, which lowers viscosity. When used at their recommended levels, only a very minimal coating is placed on the sand grains. Since some of the solvent evaporates after coating, this reduces the already low percentage of resin that needs to be removed.
