Review: It is written 1kg on the container but it is 500gr !! I didn't weight it before use so couldn't return
Review: Only thing is it doesn't require even 3% of catalyst. If 3% is used literally working time is zero because it hardens up while mixing itself. So if proper proportion for catalyst is figured out, it's a good product. It didn't require even mold release agent for resin pieces. Captured all impressions perfectly of the model piece while casting.
