  It is very important not to have any dimensional variation to avoid wastage, especially when it comes to gold.

• Are low viscosity
  Makes the RTV easy to mix, pour and vacuum, thus reducing mould rejection.

• Have Fast setting times
  Reduce delivery times and increase production.

• Have High tear strength
  Moulds last longer, giving more castings per mould, thus making it more cost effective for larger volumes.

  Hardnesses between 20-40 ShA are ideal to demould complicated wax pieces without damaging them.
