    Silicone Cure Systems - Silicone Technologies Uncured .

    Silicone elastomer can be crosslinked ("cured" or "vulcanized") into solid forms through a variety of cure systems. The most common curing systems are: 1) addition cure chemistry (platinum catalyst) which does not require moisture or open air, and 2) condensation cure (tin catalyst) chemistry which requires airborne moisture. Dual cure systems also exist, which are formulated to react with .

    Rubber Curing | Tire | Cross Link

    Rubber Curing. Systems Over the years three special types of. cure systems have been developed. They are: efficient vulcanisation (EV) systems, semi-efficient vulcanisation (SEV) systems and conventional vulcanisation (CV) systems. The levels of accelerator and sulfur in CV, SEV and EV systems are shown in Table 1 Measuring Cure

    Curing (chemistry) - Wikipedia

    Curing is a chemical process employed in polymer chemistry and process engineering that produces the toughening or hardening of a polymer material by cross-linking of polymer chains. Even if it is strongly associated with the production of thermosetting polymers, the term curing can be used for all the processes where starting from a liquid solution, a solid product is obtained.
