ZEUSLAB® and ZEUSLAB®Sd are condensation impression silicones for use in the dental laboratory, providing a high level of reproduction of details. Being soft, free-flowing and non-sticky during mixing, they become extremely hard and heat-resistant after polymerisation. There are two products, both undeformable, and completely inert in relation to acrylic resins: ZEUSLAB®, which is hard and slightly flexible, and ZEUSLAB®Sd, extra-hard.
