Premium Quality RTV Silicone Rubber for Mould Making and General Crafting
Premium Quality RTV Silicone Rubber for Mould Making. This is a high Strength silicone mould making rubber. Formulated for easy mixing by hand. The RTV and Catalyst mix easily and due to the low viscosity can be used without processing in a vacuum chamber. This silicone is suited for the detailed reproduction of figures, art objects and similar items.
Shore A Hardness
The Shore Hardness of this RTV is 35 - 45 which means this silicone when cured will have a soft to medium feel.
Add the Catalyst to the Silicone and allow to stand for a few minutes for excess air to release prior to pouring into your project mould. If there is very fine detail and you have no de gassing equipment then you can paint the mixture into very fine detail applying a thin layer of silicone first and manually burst any bubbles that occur. You must then allow the correct cure time to pass prior to de moulding. Please remember that in colder temperatures this time period my need to be extended.
RTV Silicone Rubber for all Mould Making Crafting Applications
- Mixing Ration of 100 parts to 10 Parts Catalyst
- High Detail Capability
- Long Working Time
- Good Tear Resistance
- Highly Elastic for Good Mould Release from Complex Parts
- Woring Time of 40 - 60 Minutes
- Apply to Multiple Surfaces
100 Parts Silicone to 10 Parts Catalyst
Cure times vary dependant on room temperature but allow between but 12 and 24 Hours to Release the Mould. It is important that you make sure the Silicone Rubber is Completely Cured and Dry prior to releasing your project from the mould. Please remember that in colder temperatures this time period my need to be extended.
