Casting Siliconic Rubber + accelerator
S21K PC, is a high quality 2-component addition cure silicone RTV rubber vulcanising at room temperature. It is designed for applications where very accurate dimensional reproduction of prototype parts that interconnect is required.
Vulcanised products are ideal for the use of epoxy, UP, PU and acrylic resins, concretes and gypsum.
Accurate dimensional reproduction and stability as well as high mechanical resistance make silicone rubber S21K PC ideal for the production of prototypes and moulds.
Its incredibly low shrinkage and high dimensional stability make S21K PC suitable for artistic ceramics, ceramic silk-screen printing, jeweller’s craft and concrete moulding.
S21K PC silicone rubber is compatible with most epoxy, PU and acrylic resins, gypsum and concrete.
The S21K PC silicone is sold with the SLOW H24 catalyst. The FAST H2 catalyst can be purchased separately
