Cast-a-mold 30TF

Excellent molding compound. Takes fine detail very well. Very happy with how even with slight under cuts I can still extract nice castings without mold tear out. Easy to use and it has adequate work time. Very fine product.

Cast a mold 30tf

Thick but does a good job. Seems like the molds themselves are very heavy duty.

Cast A Mold 30TF

Great Mold material for smaller molds as it has a short working time (15 minutes). For big molds this will have to be poured in multiple batches because of the short work time. It's quite thick and might cause some problems with narrow undercuts if poured to quickly. It is virtually bubble free once cured no degassing necessary.
