Tin Based Silicone
TinSil FastCat Accelerator
Use TinSil FastCat in place of any TinSil Part A in order to accelerate cure and shorten demold time. FastCat can be used in a range of 2-6 parts per 100 parts B. Often used for reducing time needed between coats when TinSil rubbers are used to make brush-on blanket molds. Use of FastCat can shorten the library life of cured TinSil rubber.

TinSil 80 Series Silicone Rubber
TinSil 80 Series Silicone Rubber
The TinSil 80-Series is 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 80-15 is a 1A:10B mix ratio tin silicone with a soft, A~15 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. As with other Polytek silicone mold rubbers, TinSil 80-15 can be used to cast all media without release agents. TinSil 80-15 can be poured as supplied or thickened with TinThix liquid additive.

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

TinThix - TinSil Thickener
A liquid thickener designed for mixing into TinSil liquid rubbers to create a creamy, thixotropic consistency for turning pourable TinSil rubbers into brushable systems. Varying levels can be added to create a light gel up to a thicker silicone rubber paste. A few drops in a cup size mix gives a nice face coat consistency. Experiment to determine your desired levels.
