Kulzer - Memosil 2. Memosil 2 is a vinyl polysiloxane that mixes automatically, flows nicely, and sets in 2 minutes. Bite registration materials based on A-silicones make it possible to produce precisely fitting restorations. Their many different uses in prosthetics, conservative dentistry, implant dentistry, and orthodontics are examples of their wide range of applications. The transparent A-silicone Memosil 2 is particularly suitable for special indications, when light-curing through the material is necessary.
