Silicone putty is new silicone compounds (platinum catalyst) that can be easiy mixed and applied by hand to a variety of usage . It has a pot life of about 5-20 mins with a cure time of about 30-60 mins at room temperature.Shrinkage is low and cured rubber is exceptionally strong (very high tensile strength) .They also resist cure inhibition. 

MC- Silicone Putty is new silicone compounds (platinum catalyst) that can be easily mixed and applied by hand to a variety of surfaces. Silicone Putty is mixed in equal amounts (1A:1B) by volume/weight, it has a pot life of about 2-3 minute with a cure time of about 5-8 min at room temperature (73°F/23°C). Shrinkage is low and cured rubber is exceptionally strong (very high tensile strength), durable and will resist high temperatures (for casting low-temperature melt metal alloys). They also resist cure inhibition. It is also FOOD SAFE and can be used for culinary applications.

1:1 mix ratio silicone putty. It picks up tiny details, so it is excellent for small molds. The putty has a work time of three minutes and a cure time of 20 minutes.
