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 use-able mold life.
TinSil 80-30 is a 1A:10B mix ratio 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.
Add TinThix thickener for brushed-on application.
