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.
