What is silicone casting rubber?

Silicone casting rubber is a versatile liquid silicone often used for making flexible moulds for copying objects. Silicone rubber is ideally suited in combination with epoxy, polyester, polyurethane, plaster, concrete and similar materials. Its self-dissolving properties and flexibility make the material very suitable when you want to copy fine details. In fact, all small details are copied exactly. Polyestershoppen supplies RESION casting rubber. This is a user-friendly product that allows you to make high-quality moulds. Moreover, you can easily remove the end result from the mould with this silicone casting rubber.

Making silicone moulds

With RESION Silicone moulding rubber, you can easily make your own silicone moulds. Silicone rubber is available in different degrees of flexibility (shore) and is also available in two varieties: Silicone moulding rubber (1:1) and Silicone moulding rubber (1:10). Silicone casting rubber 1:1 has a simple mixing ratio of 1 to 1. This means that you simply have to add 1 part base (A) and 1 part hardener (B) together to cure the silicone.

Silicone casting rubber 1:10 has a trickier mixing ratio. For optimum processing of this variant, add 10% hardener (B) to the base (A). Silicone casting rubber is available in shore 8, shore 15, shore 25 and shore 40. The higher the shore, the less flexible the mould is after curing.
