I'm considering using epoxy resin with this mold, but I'm not sure what kind of finish I'll end up with. Will the finished product be glossy or matte? This information will help me decide whether to use this mold or look for another option.
Silicone material does not inherently have a glossy or matte finish. When liquid silicone replicates a product, it mimics the surface characteristics of the original master. If the master has a glossy finish, the resulting silicone mold will also be shiny. When you remove epoxy resin from the mold, the finish of the resin will depend on the surface of the mold. Essentially, the surface finish of the resin will match the surface finish of the mold.
