liquid silicone rubber for GRC products operations:

If the customer wants to make large products and large size molds, the mold should be made of silicon rubber with high hardness. On the contrary, if the mold with fine and precision patterns, it should be made of silicon with low hardness. The amount of the curing agent depends on the actual requirements of the customer. If molds requiring fast drying and demould, more curing agent is needed; contrarily, if molds requiring slower drying and demould, less curing agent is needed.

(Note: our company does not recommend you to add silicone oil. If a special soft silicon mold or fine detailed and complex patterns products are required, 5%-10% silicone oil can be added to soften the mold for easy demould.)

liquid silicone rubber for GRC products FAQ:

How to reduce the shrinkage?

1) Control the addition of catalyst. Usually, more catalyst would be added if you want to cured fast, but still we can adjust the working time and the curing time as you require.

2) Do not remould so fast, and pls let the silicone mold cured completely, which would take about 24 hours, then remould.

3) When you produce the products, pls put the mold flatly, then pour the plaster or other materials into it smoothly. When you do not usually the mold, you should store it flatly, not fold it, and you also can pour the plaster into it and not remould the finished plaster products, leaving it in the mold to keep the mold in original shape.
