(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.)

FAQ of Concrete Molding RTV Liquid Silicone   

About the shrinkage, Leah have some other suggestion on how to reduce it for you.

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 plater 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 fisinished plaster products, leaving it in the mold to keep the mold in original shape.
