Molds for plaster and reconstructed stone
Special polyurethanes, elastomers and silicone rubbers for both polyaddition and polycondensation have been specifically conceived for the creation of molds to be used “on site” for molded concrete. The peculiarities of the systems are high hardness, excellent resistance to the basicity of the concrete and a good tear strenght as regards polyurethanes, while silicones stand out for the ease of application, the excellent ability to copy the surface and a very good elongation.
