Important! If you are looking for a lower cost alternative to 80-30, we recommend 5092. One of the reasons for 80-30's high cost is its compliance with FDA "food-safe" regulations. 5092 is not tested for food contact but it is a great formula for resin casting and lost was patterns. As they say in the magic world,"don't run if you aren't being chased!" If you do not need food contact compliance, don't pay for it! It is much less expensive but still has great physical properties and 3 different catalysts.

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.
