RTV: Room Temperature Vulcanizing
Urethane RTV is a two-part system that cures a flexible and high strength Shore-A 30 mold rubber (for comparison purposes, household silicone sealant is approximately Shore-30). Excellent tear resistance is another benefit of Urethane, yet it is easy to cut for two-piece molds. Urethane is an easy-releasing rubber for casting gypsum plasters and waxes without release agents and is excellent for casting cement, epoxy, polyester, or Urethane with proper release agents.
