TUFSIL 28 CONDENSATION SILICONE RUBBER

Due to the excellent mechanical properties of the cured rubber as well as its high resistance to casting resin, TUFSIL®28 is especially suitable for reproducing parts in Polyurethane, Polyester and Gypsum Cements. Other materials, such as wax and plaster, may be cast without any problems in moulds made from TUFSIL® 28. A 20kg pail of silicone is supplied with 800gm of catalyst, which is more than the recommended 2.5%. The catalyst may be adjusted to suit your climate and processing conditions. Please test alternate catalyst ratios before undertaking large projects.
