Description: It is a fast-curing, food-safe silicone putty, a new type of silicone compound (platinum catalyst), easy to mix, and can be manually applied to different surfaces. Mix silicone putty with equal volume/weight (1A:1B). At room temperature (73°F / 23°C), the pot life is about 3 to 15 minutes, and the curing time is about 30 to 60 minutes. Vulcanized rubber with low shrinkage is very strong (very high tensile strength), durable and resistant to high temperatures (used to cast molten metal alloys at low temperatures). They also resist curing delays. characteristic: -High temperature resistance. -Easy to use, working time 3-15 minutes, curing 30-60 minutes. -Ideal for small molds with excellent original details. -Support A35, strong, flexible, reusable shape. -High heat range, up to 400oF. -No shrinkage. -Release agent, no release agent is needed in most applications. -Odorless and non-toxic. Meet FDA food grade standards. specification: Material: Silicone rubber Color: blue, white Main application: solid silicon Appearance: Semi-liquid Viscosity: 20000 Temperature: 200 (℃) Mixing ratio 1:1 Shelf life (minutes): 3-5 minutes Hardening time (hours): 30-60 minutes Tensile strength (MPa): 2.5 Tensile break: 350% Hardness (Shore hardness A): 35 Shore hardness A Shrinkage rate: 0.1%
