TinSil 80-30 is the first in a new series of tin-cured silicone mold rubbers from Polytek that are designed to offer reduced shrinkage upon cure and during casting, longer storage/library life once cured and longer useable mold life.
TinSil 80-30 is a 1A:10B mix ratio (by weight) tin silicone with a mid-range, A~30 hardness and a tough, snappy, high-tear cure. The highest performance materials and processes have been used to develop this next-generation tin silicone for the most demanding casting applications.
Can be used for poured molds or use TinThix to thicken for brushable molds.

As with other Polytek silicone mold rubbers, TinSil 80-30 can be used to cast all media without release agents.
TinSil 80-30 may be used for food contact applications.
