Platinum Cure Silicone is Ideal For:

  • Concrete molds
  • Jewelry molds
  • Pewter molds
  • Candle and soap molds
  • Precision molds for the rapid prototyping industry
  • Molds with multiple components that snap or fit together

There are limitless casting materials that are best cast into silicone molds including:

  • Epoxy Resin
  • Candle wax
  • Foundry wax
  • Plaster
  • Concrete
  • Soap
  • Low melt metals
  • Hot metal glue

Rapid prototyper’s who make some of the most precise parts in the world use platinum cure silicone for true-to-life accuracy in replication. It’s an essential ingredient when making parts that fit or snap together. Addition cure silicones are sensitive to inhibition which can show itself as localized sticky areas. To avoid inhibition substances to keep away from include :

  • Condensation (tin) cure silicone
  • Clay containing sulphur
  • Amines (in some epoxies)
  • Latex
  • Natural rubbers
  • Powder on latex gloves (the gloves too!)
  • Nitrogen oxide
  • Carbon monoxide
