Demoulding in around 2 to 4 hours @ 25 degrees. Low 0.01% Shrinkage on large scale moulds. If mould is adhesive after 24 hours this is due to temperature been too cold. You can fix this by placing mould in a hot room @ 25 degrees or wait 3 - 5 days and this will go away.


It is recommended when pouring large casting moulds to set silicone for at least 12 hours before demoulding.

Work in a well-ventilated area. Avoid contact with eyes and skin. Wear protective gloves and glasses when mixing and using. Over-exposure may cause sensitization. Uncured material can be removed with a solvent or methylated spirit followed by washing
with warm soapy water. Always wear a mask when using any solvent cleaner.
