These molds are designed to make fine pieces of polyurethane resin.
Resin is an aggressive material for silicones, this is always the case, our silicone is of very high quality and we can make dozens of pieces until it begins to deteriorate. We can extend the life of our mold with silicone mold release spray.
It is very fast to reproduce and create pieces with resin, the result is thin pieces and easy to cut, modify and assemble. The buildings created are of high resistance and an excellent price in resin / weight ratio.
