2 different things, curing sealer and post cure sealer. The first one washes off.
AFA the temps go, as long as the new pour doesn't freeze while it still has a high water content, it will be OK. The exothermic reaction should protect it for the first day unless it gets just way to cold for an extended amount of time. Any real danger and the contractor would have covered it to keep the heat in.
