... is also good. However, a health hazard must be noted: the by-product of curing at 275 to 315 °C (525 to 600 °F) is ammonia. The hot box process uses either organic furan or phenolic liquid thermosetting resin or a blend of the two. Today (2016), approximately 90% of the resins used for the hot box...

In the hot coating process, moisture is generally not a problem, because it is driven off when the sand is heated to the minimum...
