Casting Siliconic rubber
S40K PA, 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 S40K PA ideal for the production of prototypes and moulds.
Its incredibly low shrinkage and high dimensional stability make S40K PA suitable for artistic ceramics, ceramic silk-screen printing, jeweller’s craft and concrete moulding.
S50K PA silicone rubber is compatible with most epoxy, PU and acrylic resins, gypsum and concrete.
