RTV Silicone Rubber for gypsum moulding
1. RTV Silicone Rubber for gypsum moulding usages
RTV Silicone Rubber for gypsum moulding is primarily intended for mold making of gypsum, concrete, poly resin ,PU resin, unsaturated resin crafts, lighting and candles crafts , plastic toys , stationery gifts crafts industry, large statue, Buddha, relievo furniture, furniture decorative materials, statues Buddha, artifacts copied, building decoration materials, large-scale cement mold, artificial fossils Factory, European buildings, simulation landscapes, animals and plants sculpture, sandstone crafts and so on.
2. RTV Silicone Rubber for gypsum moulding main features
RTV Silicone Rubber for gypsum moulding is white or red flowing liquid with general hardness of 22-50 shore A ,after curing. Molding silicon rubber is a kind elastic silicon rubber mold which features with resistance to deformation, high-temperature, acid-alkali and expansion as well as high reproduction times, good tensile strength ,tear strength and elongation.
3. RTV Silicone Rubber for gypsum moulding discription
RTV Silicone Rubberfor gypsum moulding is a kind of flowable liquid silicone, the quality has nothing to do with the color. It consists of two components. Part A is a flowable liquid silicone rubber, part B is the curing agent. Firstly, after your previous work of dealing with the original model, take some liquid silicone rubber , add 2%-3% curing agent of the amount of silicon, and mix them evenly. Then after vacuum-pumping the mixture, you can pour it into the mold frame. The silicone mold will cured in 2-4 hours.
And more curing agent is needed; contrarily, if molds requiring slower drying and demould, less curing agent is needed.

5. RTV Silicone Rubber for gypsum moulding frequently asked question
Why does the silicone mold appear to be dry outside but wet inside?
Because molding silicone rubber is a kind of condensation silicone rubber, which get solidified after absorbing moisture from the air. In order to provide a significant shelf-life for the silicon rubber, we will dry out the water in the silicon rubber.
Solution: Add 0.05% water into the silicon rubber and Stir over a low speed briefly when you use it.
