RTV Silicone Rubber for Art Crafts Mold Making (HY625) FAQ
1. Why does the mold made of silicone rubber have an unsmooth surface with tracks and strips on it?
It is due to product or model to be molded should hasn't been sanded or polished. If the mold or product is not sanded or polished, the mold made of whatever quality silicone rubber will not be good and smooth enough since the mold or the product itself is not smooth or perfect. Another case is that uneven brushing of the release agent will also bring about unsmoothness of the mold.
