What is RTV silicone rubber?
RTV Silicone (room temperature vulcanizing silicone) is a type of silicone rubber made from a two-component system (base plus curative; A+B) available in a hardness range of very soft to medium - usually from 15 Shore A to 40 Shore A. RTV Silicones can be cured with either a platinum catalyst or a tin catalyst.
What does RTV-2 mean?
Two components when mixed together cure at room temperature (RTV= room temperature vulcanization).
Features of RTV silicone rubber
1. Good characteristics of easy-operation
2. Light viscosity and good flow ability
3. Low shrinkage
4. Favorable tension
5. No deformation
6. Favorable hardness
7. High temperature resistance, acid and alkali-resistance and ageing resistance
Why choose RTV-2 silicone rubber to make mold?
RTV-2 silicone rubber is used primarily in the mold-making industry. Silicone molds are durable, simple to construct and use, and can be used for most castable materials.
Do I need to use a mold release?
Yes, on the original, and when trying to separate two silicones halves. Silicone will only stick to itself and it does it quite well. You do not need to release your reproductions as silicone once it is cured is self releasing.
Do I have to deair/degas the silicone before pouring?
The silicone will work better if you vacuum degas it. By removing all the extra air you mixed into it, the silicone will pick up better detail and have stronger physical properties. All the properties listed on the data sheet are obtained from a degassed sample. However, degassing does not effect the curing.
What is the shelf life?
The shelf life of the uncured material is 6 months. The "library" life that is the life of the cured silicone varies from product to product and you should check with the factory.
