Unlike addition cure silicone rubber, the cure speed of condensation cure silicone rubber (such as our CS25) is not increased with the addition of heat. A silicone system that uses a platinum-based catalyst (a so-called addition curing silicone) are sensitive to certain compounds that prevent curing reactions from taking place. In the case of silicone curing, it makes it more difficult to get a silicone to cure. • An evaluation of polysulfides, poly ethers, and condensation and addition silicones with a variety of disinfectants was conducted. Unlike urethanes, they do not require the costly use of ovens to thoroughly dry components before processing. – They are the most accurate, stable, and expensive impression materials. Results: This material is often called a polyvinyl siloxane (PVS) or vinyl polysiloxane (VPS) impression material. Condensation cure reactions actually need some ambient moisture and so you will often find that using an oven to try to speed up the cure has the opposite effect and actually slows down the cure of condensation cure silicones. The poison thereby prevents the curing reaction to proceed permanently. Dimensional stability and accuracy of an impression after chemical disinfection by immersion in disinfectants are crucial for the accuracy of final prosthetic restorations. This can be used on purpose to control when and how fast a certain silicone product cures and to control its pot life (time from mixing of part A and B until the mixture’s viscosity has doubles, i.e. Tin (Sn): Are present in for example 1-component silicone ahesives (condensation curing) as well as 2-component condensation curing silicones.
