Silicone rubber for making grc molds with low shrinkage
1.Silicone rubber for making grc molds with low shrinkage usages
Silicone rubber for making grc molds 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.Silicone rubber for making grc molds with low shrinkage features
1.Good resistance to deformation, high-temperature, acid-alkali and expansion
2.High reproduction times
3.Good tensile strength ,tear strength and elongation.
3. Silicone rubber for making grc molds with low shrinkage discription
Silicone rubber for making grc molds 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. Silicone rubber for making grc molds with low shrinkage 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.
Need the price or other information for reference,please feel free to confirm with us some question at first
1) How about the size of your products?
2) Will you make the silicone mold by pouring way or brushing way ?
3) What's the raw material of your products ? Plaster? resin or other?
Then we will according it to recommend the most suitable silicone with the best price for your reference
