Important Notes:
-The 3 hour work time is the standard in-stock product. 60, 90 and 240 minute work times 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. For more info, contact our Tech Dept.
WARNING: This product can expose you to chemicals including N-Methylpyrrolidone, which are known to the State of California to cause cancer and birth defects or other reproductive harm. For more information, go to www.P65Warnings.ca.gov.
