Polyaddition Base and Catalyst
Choose from our available polyaddition silicones. These are two component, Room Temperature Vulcanizing (RTV-2) silicone rubbers that are catalyzed using platinum. Polyaddition silicones are used in applications including rapid prototyping, 3D printing, and pad printing were high dimensional accuracy and low/no shrinkage is required.
Select a polyaddition catalyst to help meet your application needs for durometer/hardness.
This table shows single components available and their properties. Please see our available kits for combined base and catalysts.
