Platinum Silicone for Concrete/Cement Mold Making
Concrete casting stone materials or faux stone manufacturing allows you to reproduce detailed and accurate copies of designs. Faux stone, also known as cultured stone or manufactured stone, is used to create a variety of parts like stone columns and exterior wall sidings or veneers. Concrete casting is also used with indoor features such as faux stone fireplaces, accent walls, and other decorative architectural parts. In order to ensure that your design is reproduced accurately each time, it is important to have a mold made from the right material. Silicone molds are time tested and proven to be the mold making material of choice in high quality concrete part reproduction.
In some cases, polyurethane and latex materials have been used in the concrete casting process. However, these materials are problematic due to high and inconsistent levels of shrinkage. High shrinkage of mold materials does not provide the level of dimensional stability required to produce high quality faux stones used in veneers or panels. Silicone, with its very low shrinkage and excellent release characteristics, provides the required dimensional stability necessary to produce highly accurate part geometries for today's modern aesthetics and precision.
Product description

Warm tips :
As platinum cure silicone is very sensitive, please avoid to mixing with the following materials, otherwise the silicone won't be cured :
- Do not mix with liquid condensation silicone rubber or even the tool which used for condensation silicone.
- Do not mix with organic matter which contains N, S, P organics and ionic compound like Sn, As,Hg, Ph,
- Do not add any pigment or powder into the platinum cure silicone without testing
