Hello! I am searching for material. I need to find some substance which in begining is like a wire (can be deformed as I want), but in few minutes after warming/contact with air/mixing with something it hardens and become like plastic without possibility to deform it. May be someone know such substance? Thanks

Shape memory alloy?  One of those UV curing epoxy resins?

Thanks for your reply!
Yes, UV curing epoxy resins are not so convinient fo my needs, but it's near.
I have read about polyurethane resin, which after contact with water becomes hard like plastic. It is used in surgery synthetic casts. It is the best variant fo me. But what is a structure or name of it - I dont know
