PlatSil platinum silicone mold rubbers are used primarily for polyurethane resin and polyurethane foam casting. This includes making molds to reproduce cold cast bronze art where the resin binder is EasyFlo 60 or EasyFlo Clear. PlatSil rubbers do not exhibit shrinkage upon curing so they are useful for casting dimensionally stable parts for highly accurate prototyping and model making applications. PlatSil rubbers do not require release agent when casting and do not have a limited library life as do tin silicone mold rubbers. Caution should be taken to insure objects that come in contact with PlatSil liquid rubbers are not contaminated with amines, sulfur, tin compounds and others which may inhibit the cure of the system. PlatSil rubbers can be poured as supplied or thickened with PlatThix liquid thickener for brush-on molds. PlatSil 71-Series offer low to firm hardness rubbers some of which are easy 1:1 mix ratios. PlatSil 73-Series systems offer mid range to harder rubbers for industrial silicone rubber mold making applications. PlatSil Gel systems are 1:1 mix soft silicone rubbers that are designed for special effects make up applications. PlatSil Gels can be used as supplied in A~10 or OO~30 hardness versions or can be modified with additive such a Smith's Theatrical Prosthetic Deadener to mimic and tissue consistency!
