CHT SilSo Print 21001 Silicone Rubber
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber
Material Notes:	Description: Pourable, addition-curing, 2-part silicone rubber that cures at room temperature. This product is mainly used for making silicone printing pads. The cured rubber exhibits excellent physical and electrical properties. Fast and non-shrink cure at room temperature which can be accelerated considerably by the application of heat. Key Features The product can be diluted by adding silicone oil (50 – 300 mPas), which reduces the viscosity and hardness of the material. Very good flow and detail reproduction properties due to low viscosity. very good mechanical properties, even diluted. Ink resistance. Information provided by CHT Group
