It's common to see "ice beams" that are able to freeze enemies or objects. Freezing a large object solid takes time, so most freeze rays aren't practical or logical, especially after factoring in differences in the material of the object.
As an alternate approach, is there a feasible way to snap-freeze water or another substance in a way that it freezes around an object? Is there a practical way to completely surround a human or other large object near instantly with a thick enough coating of ice/frozen material as to prevent movement?
Something such as a jet of a two liquids that chemically react and instantly crystallize, but without generating heat. I'm looking for something with an endothermic effect in particular, even if minor.
Hurdles to this question include variances in outside temperature (the effect should still be possible in Earthly temperature ranges, maybe 15C - 50C).
