Important Notes:

The 15-minute work time is the standard in-stock product.  30 minute work time may take 1-3 days to ship.  

Demold time is totally dependent on work time and the concentrated mass of the cast part.  Thin walled parts cast with longer work time systems may not cure well without heat.  Larger mass parts will cure faster and more complete at room temperature compared to thinner parts.  Please contact BJB Tech Sales for help with selecting the correct system for your application.

Silicone Molds: Platinum based silicones are recommended for molds.  Tin based silicones may potentially cause cure inhibition, however, contact our Tech Dept. for guidance on silicone molds if you are unsure.
