PlatSil 73-15 Precision Silicone -Gallon Kit (16 lb Kit)
PlatSil 73-15 Precision Silicone is a ultra low viscosity, high elongation, 1:1 RTV Silicone Rubber, that has a 30 minute working time and a 4 hour demold time. It cures a Hazy Translucent color.
PlatSil® 73-15 Precision Siliconeis recommended for evaluation as a mold material for polyester, epoxy and polyurethane resins, as well as for waxes and many other materials. PlatSil® 73-15 offers advantages over tin-catalyzed systems in certain applications because on curing it doesn’t shrink, it doesn’t produce alcohol (like tin-catalyzed silicones) which can inhibit urethane castings, and it can be heat accelerated to speed the cure.
PlatSil 73-15 is used by Neill Gorton in The Art of Silicone Prosthetics DVD Series.
No release agent is necessary for casting most materials in PlatSil® 73-15 Precision Silicone molds, but for a longer mold life with epoxy, polyurethane or polyester resins, a barrier coat or release agent, (i.e., Pol-Ease® 2300) is recommended. Properly cured PlatSil® 73-15 molds last for years without deterioration.
