Bluesil RTV 3318

Bluesil (formerly Rhodorsil) RTV 3318 is a silicone elastomer which, after the addition of a catalyst, cures at room temperature and leads to a flexible and elastic material. RTV 3318 is excellent for making moulds for the production of parts made of different materials, such as plaster, wax, acrylic resin, polyester resin, epoxy resin, as well as silicone elastomers.
