There is also a method of reacting bisphenols with formaldehyde (see, for example, Japanese Patent Laid-Open No. 56-47239). These foundry sand binder compositions had the drawbacks of low heat resistance, too good disintegration, and sand spilling out during pouring. For this reason, during the casting process, the sand used as the core gets stuck in the pouring ring, deteriorating the working environment and requiring extra man-hours to remove it.
